## Variables

const bool | use_exceptions = true
| Alias for 'true', to make code requesting exceptions more readable.
bool | dont_quote_auto = false
| Set to true if you want to suppress automatic quoting.
const null_type | null = null_type()
| Global 'null' instance. Use wherever you need a SQL null. (As opposed to a C++ language null pointer or null character.).

## Detailed Description

All global symbols in MySQL++ are in namespace mysqlpp. This is needed because many symbols are rather generic (e.g. Row, Query...), so there is a serious danger of conflicts.

## Enumeration Type Documentation

enum mysqlpp::do_nothing_type0

The 'do_nothing' manipulator.

Does exactly what it says: nothing. Used as a dummy manipulator when you are required to use some manipulator but don't want anything to be done to the following item. When used with SQLQueryParms it will make sure that it does not get formatted in any way, overriding any setting set by the template query.

Enumeration values:

  do_nothing | insert into a std::ostream to override manipulation of next item

enum mysqlpp::escape_type0

| The 'escape' manipulator. Calls mysql_escape_string() in the MySQL C API on the following argument to prevent any special SQL characters from being interpreted.

enum mysqlpp::ignore_type0

The 'ignore' manipulator.

Only valid when used with SQLQueryParms. It's a dummy manipulator like the do_nothing manipulator, except that it will not override formatting set by the template query. It is simply ignored.

Enumeration values:

  ignore | insert into a std::ostream as a dummy manipulator

enum mysqlpp::quote_double_only_type0

The 'double_quote_only' manipulator.

Similar to quote_only manipulator, except that it uses double quotes instead of single quotes.

Enumeration values:

  quote_double_only | insert into a std::ostream to double-quote next item

enum mysqlpp::quote_only_type0

The 'quote_only' manipulator.

Similar to quote manipulator, except that it doesn't escape special SQL characters.

Enumeration values:

  quote_only | insert into a std::ostream to single-quote next item

enum mysqlpp::quote_type0

The standard 'quote' manipulator.

Insert this into a stream to put single quotes around the next item in the stream, and escape characters within it that are 'special' in SQL. This is the most generally useful of the manipulators.

Enumeration values:

  quote | insert into a std::ostream to single-quote and escape next item

## Function Documentation

template<class Container>
void mysqlpp::create_vector | ( | const Container & | c,
|  | std::vector< bool > & | v,
|  | std::string | s0,
|  | std::string | s1,

|  | std::string | s8,
|  | std::string | s9,
|  | std::string | sa,
|  | std::string | sb,
|  | std::string | sc
| ) |

Create a vector of bool using a list of named fields.

This function is used with the ResUse and Result containers, which have a field_num() member function that maps a field name to its position number. So for each named field, we set the bool in the vector at the corresponding position to true.

This function is used within the library to build the vector used in calling the vector form of Row::equal_list(), Row::value_list(), and Row::field_list(). See the "Harnessing SSQLS Internals" section of the user manual to see that feature at work.

void mysqlpp::create_vector | ( | size_t | size,
|  | std::vector< bool > & | v,
|  | bool | t0,
|  | bool | t1 = false,
|  | bool | t2 = false,

|  | bool | t4 = false,
|  | bool | t5 = false,
|  | bool | t6 = false,
|  | bool | t7 = false,
|  | bool | t8 = false,
|  | bool | t9 = false,
|  | bool | ta = false,
|  | bool | tb = false,
|  | bool | tc = false
| ) |

Create a vector of bool with the given arguments as values.

This function takes up to 13 bools, with the size parameter controlling the actual number of parameters we pay attention to.

This function is used within the library to build the vector used in calling the vector form of Row::equal_list(), Row::value_list(), and Row::field_list(). See the "Harnessing SSQLS Internals" section of the user manual to see that feature at work.

| Constructs a equal_list_b (sparse equal list). Same as equal_list(Seq&, Seq&, const char*, bool, bool...) except that it doesn't take the const char* argument. It uses a comma for the delimiter. This form is useful for building simple equals lists, where no manipulators are necessary, and the default delimiter and equals symbol are suitable.

| Constructs a equal_list_b (sparse equal list). Same as equal_list(Seq&, Seq&, const char*, const char*, Manip, vector<bool>&) except that it takes boolean parameters instead of a list of bools.

template<class Seq1, class Seq2, class Manip>
equal_list_b<Seq1, Seq2, Manip> equal_list | ( | const Seq1 & | s1,
|  | const Seq2 & | s2,
|  | const char * | d,
|  | const char * | e,
|  | Manip | m,
|  | const std::vector< bool > & | vb
| ) |

| Constructs a equal_list_b (sparse equal list). Same as equal_list(Seq&, Seq&, const char*, const char*, Manip) except that you can pass a vector of bools. For each true item in that list, operator<< adds the corresponding item is put in the equal list. This lets you pass in sequences when you don't want all of the elements to be inserted into a stream.

template<class Seq1, class Seq2, class Manip>
equal_list_ba<Seq1, Seq2, Manip> equal_list | ( | const Seq1 & | s1,
|  | const Seq2 & | s2,
|  | const char * | d,
|  | const char * | e,
|  | Manip | m
| ) |

| Constructs an equal_list_ba. Same as equal_list(Seq&, Seq&, const char*, const char*) except that it also lets you specify the manipulator. Use this version if the data must be escaped or quoted when being inserted into a stream.

template<class Seq1, class Seq2>
equal_list_ba<Seq1, Seq2, do_nothing_type0> equal_list | ( | const Seq1 & | s1,
|  | const Seq2 & | s2,
|  | const char * | d = ",",
|  | const char * | e = " = "
| ) |

Constructs an equal_list_ba.

This function returns an equal list that uses the 'do_nothing' manipulator. That is, the items are not quoted or escaped in any way when inserted into a stream. See equal_list(Seq, Seq, const char*, const char*, Manip) if you need a different manipulator.

The idea is for both lists to be of equal length because corresponding elements from each list are handled as pairs, but if one list is shorter than the other, the generated list will have that many elements.

Parameters:

  s1 | items on the left side of the equals sign when the equal list is inserted into a stream
  s2 | items on the right side of the equals sign
  d | delimiter operator<< should place between pairs
  e | what operator<< should place between items in each pair; by default, an equals sign, as that is the primary use for this mechanism.

template<class BinaryPred, class CmpType>
MysqlCmp<BinaryPred, CmpType> mysql_cmp | ( | uint | i,
|  | const BinaryPred & | func,
|  | const CmpType & | cmp2
| ) |

Template for function objects that compare any two objects, as long as they can be converted to SQLString.

This is a more generic form of mysql_cmp_cstr(), and is therefore less efficient. Use this form only when necessary.

Parameters:

  i | field index number
  func | one of the functors in compare.h, or any compatible functor
  cmp2 | what to compare to

template<class BinaryPred>
MysqlCmpCStr<BinaryPred> mysql_cmp_cstr | ( | uint | i,
|  | const BinaryPred & | func,
|  | const char * | cmp2
| ) |

Template for function objects that compare any two things that can be converted to `const char*`.

Parameters:

  i | field index number
  func | one of cstr_equal_to, cstr_not_equal_to, cstr_less, cstr_less_equal, cstr_less_equal, or cstr_less_equal.
  cmp2 | what to compare to

template<class Seq, class Manip>
std::ostream& operator<< | ( | std::ostream & | o,
|  | const value_list_b< Seq, Manip > & | cl
| ) |

| Same as operator<< for value_list_ba, plus the option to suppress insertion of some list items in the stream. See value_list_b's documentation for examples of how this works.

template<class Seq, class Manip>
std::ostream& operator<< | ( | std::ostream & | o,
|  | const value_list_ba< Seq, Manip > & | cl
| ) |

Inserts a value_list_ba into an std::ostream.

Given a list (a, b) and a delimiter D, this operator will insert "aDb" into the stream.

See value_list_ba's documentation for concrete examples.

  value_list()

template<class Seq1, class Seq2, class Manip>
std::ostream& operator<< | ( | std::ostream & | o,
|  | const equal_list_b< Seq1, Seq2, Manip > & | el
| ) |

| Same as operator<< for equal_list_ba, plus the option to suppress insertion of some list items in the stream. See equal_list_b's documentation for examples of how this works.

template<class Seq1, class Seq2, class Manip>
std::ostream& operator<< | ( | std::ostream & | o,
|  | const equal_list_ba< Seq1, Seq2, Manip > & | el
| ) |

Inserts an equal_list_ba into an std::ostream.

Given two lists (a, b) and (c, d), a delimiter D, and an equals symbol E, this operator will insert "aEcDbEd" into the stream.

template<>
MYSQLPP_EXPORT std::ostream& operator<< | ( | escape_type1 | o,
|  | char *const & | in
| ) | `[inline]`

| Inserts a C string into a stream, escaping special SQL characters. This version exists solely to handle constness problems. We force everything to the completely-const version: operator<<(escape_type1, const char* const&).

template<class T>
std::ostream& operator<< | ( | escape_type1 | o,
|  | const T & | in
| ) | `[inline]`

| Inserts any type T into a stream that has an operator<< defined for it. Does not actually escape that data! Use one of the other forms of operator<< for the escape manipulator if you need escaping. This template exists to catch cases like inserting an `int` after the escape manipulator: you don't actually want escaping in this instance.

template<>
MYSQLPP_EXPORT std::ostream & mysqlpp::operator<< | ( | escape_type1 | o,
|  | const ColData_Tmpl< const_string > & | in
| ) |

| Inserts a ColData with const string into a stream, escaping special SQL characters. Because ColData was designed to contain MySQL type data, we may choose not to escape the data, if it is not needed.

template<>
MYSQLPP_EXPORT std::ostream & mysqlpp::operator<< | ( | escape_type1 | o,
|  | const ColData_Tmpl< std::string > & | in
| ) |

| Inserts a ColData into a stream, escaping special SQL characters. Because ColData was designed to contain MySQL type data, we may choose not to escape the data, if it is not needed.

template<>
MYSQLPP_EXPORT std::ostream & mysqlpp::operator<< | ( | escape_type1 | o,
|  | const char *const & | in
| ) |

| Inserts a C string into a stream, escaping special SQL characters. Because C's type system lacks the information we need to second- guess this manipulator, we always run the escaping algorithm on the data, even if it's not needed.

template<>
MYSQLPP_EXPORT std::ostream & mysqlpp::operator<< | ( | escape_type1 | o,
|  | const std::string & | in
| ) |

| Inserts a C++ string into a stream, escaping special SQL characters. Because std::string lacks the type information we need, the string is always escaped, even if it doesn't need it.

MYSQLPP_EXPORT SQLQueryParms & mysqlpp::operator<< | ( | escape_type2 | p,
|  | SQLString & | in
| ) |

| Inserts a SQLString into a stream, escaping special SQL characters. We actually only do the escaping if in.is_string is set but in.dont_escape is not. If that is not the case, we insert the string data directly.

template<>
ostream& operator<< | ( | quote_double_only_type1 | o,
|  | const ColData_Tmpl< const_string > & | in
| ) |

| Inserts a ColData with const string into a stream, double-quoted ("). Because ColData was designed to contain MySQL type data, we may choose not to actually quote the data, if it is not needed.

template<>
ostream& operator<< | ( | quote_double_only_type1 | o,
|  | const ColData_Tmpl< string > & | in
| ) |

| Inserts a ColData into a stream, double-quoted ("). Because ColData was designed to contain MySQL type data, we may choose not to actually quote the data, if it is not needed.

SQLQueryParms& operator<< | ( | quote_double_only_type2 | p,
|  | SQLString & | in
| ) |

| Inserts a SQLString into a stream, double-quoting it (") unless it's data that needs no quoting. We make the decision to quote the data based on the in.is_string flag. You can set it yourself, but SQLString's ctors should set it correctly for you.

template<>
ostream& operator<< | ( | quote_only_type1 | o,
|  | const ColData_Tmpl< const_string > & | in
| ) |

| Inserts a ColData with const string into a stream, quoted. Because ColData was designed to contain MySQL type data, we may choose not to actually quote the data, if it is not needed.

template<>
ostream& operator<< | ( | quote_only_type1 | o,
|  | const ColData_Tmpl< string > & | in
| ) |

| Inserts a ColData into a stream, quoted. Because ColData was designed to contain MySQL type data, we may choose not to actually quote the data, if it is not needed.

SQLQueryParms& operator<< | ( | quote_only_type2 | p,
|  | SQLString & | in
| ) |

| Inserts a SQLString into a stream, quoting it unless it's data that needs no quoting. We make the decision to quote the data based on the in.is_string flag. You can set it yourself, but SQLString's ctors should set it correctly for you.

Query& operator<< | ( | Query & | o,
|  | const ColData_Tmpl< const_string > & | in
| ) |

| Insert a ColData with const string into a SQLQuery. This operator appears to be a workaround for a weakness in one compiler's implementation of the C++ type system. See Wishlist for current plan on what to do about this.

Query& operator<< | ( | Query & | o,
|  | const ColData_Tmpl< string > & | in
| ) |

| Insert a ColData into a SQLQuery. This operator appears to be a workaround for a weakness in one compiler's implementation of the C++ type system. See Wishlist for current plan on what to do about this.

ostream& operator<< | ( | ostream & | o,
|  | const ColData_Tmpl< const_string > & | in
| ) |

| Inserts a ColData with const string into a stream. Because ColData was designed to contain MySQL type data, this operator has the information needed to choose to quote and/or escape the data as it is inserted into the stream, even if you don't use any of the quoting or escaping manipulators.

ostream& operator<< | ( | ostream & | o,
|  | const ColData_Tmpl< string > & | in
| ) |

| Inserts a ColData into a stream. Because ColData was designed to contain MySQL type data, this operator has the information needed to choose to quote and/or escape the data as it is inserted into the stream, even if you don't use any of the quoting or escaping manipulators.

template<>
ostream& operator<< | ( | quote_type1 | o,
|  | const ColData_Tmpl< const_string > & | in
| ) |

| Inserts a ColData with const string into a stream, quoted and escaped. Because ColData was designed to contain MySQL type data, we may choose not to actually quote or escape the data, if it is not needed.

template<>
ostream& operator<< | ( | quote_type1 | o,
|  | const ColData_Tmpl< string > & | in
| ) |

| Inserts a ColData into a stream, quoted and escaped. Because ColData was designed to contain MySQL type data, we may choose not to actually quote or escape the data, if it is not needed.

template<>
ostream& operator<< | ( | quote_type1 | o,
|  | const char *const & | in
| ) |

| Inserts a C string into a stream, quoted and escaped. Because C strings lack the type information we need, the string is both quoted and escaped, always.

template<>
ostream& operator<< | ( | quote_type1 | o,
|  | const string & | in
| ) |

| Inserts a C++ string into a stream, quoted and escaped. Because std::string lacks the type information we need, the string is both quoted and escaped, always.

SQLQueryParms& operator<< | ( | quote_type2 | p,
|  | SQLString & | in
| ) |

Inserts a SQLString into a stream, quoted and escaped.

If in.is_string is set and in.dont_escape is not set, the string is quoted and escaped.

If both in.is_string and in.dont_escape are set, the string is quoted but not escaped.

If in.is_string is not set, the data is inserted as-is. This is the case when you initialize SQLString with one of the constructors taking an integral type, for instance.

MYSQLPP_EXPORT std::ostream & mysqlpp::operator<< | ( | std::ostream & | os,
|  | const DateTime & | dt
| ) |

Inserts a DateTime object into a C++ stream in a MySQL-compatible format.

The date and time are inserted into the stream, in that order, with a space between them.

Parameters:

  os | stream to insert date and time into
  dt | date/time object to insert into stream

MYSQLPP_EXPORT std::ostream & mysqlpp::operator<< | ( | std::ostream & | os,
|  | const Time & | t
| ) |

Inserts a Time object into a C++ stream in a MySQL-compatible format.

The format is HH:MM:SS, zero-padded.

Parameters:

  os | stream to insert time into
  t | time to insert into stream

MYSQLPP_EXPORT std::ostream & mysqlpp::operator<< | ( | std::ostream & | os,
|  | const Date & | d
| ) |

Inserts a Date object into a C++ stream.

The format is YYYY-MM-DD, zero-padded.

Parameters:

  os | stream to insert date into
  d | date to insert into stream

template<class Strng, class T>
Strng stream2string | ( | const T & | object | ) |

| Converts a stream-able object to any type that can be initialized from an `std::string`. This adapter takes any object that has an `out_stream()` member function and converts it to a string type. An example of such a type within the library is mysqlpp::Date.

| Constructs a sparse value list. Same as value_list(Seq&, const char*, Manip, bool, bool...) but without the Manip or delimiter parameters. We use the do_nothing manipulator, meaning that the value list items are neither escaped nor quoted when being inserted into a stream. The delimiter is a comma. This form is suitable for lists of simple data, such as integers.
