- This structure is used to define bind information, and
- internally by the client library.
- Public members with their descriptions are listed below
- (conventionally `On input' refers to the binds given to
- mysql_stmt_bind_param, `On output' refers to the binds given
- to mysql_stmt_bind_result):
-
- buffer_type - One of the MYSQL_* types, used to describe
- the host language type of buffer.
- On output: if column type is different from
- buffer_type, column value is automatically converted
- to buffer_type before it is stored in the buffer.
- buffer - On input: points to the buffer with input data.
- On output: points to the buffer capable to store
- output data.
- The type of memory pointed by buffer must correspond
- to buffer_type. See the correspondence table in
- the comment to mysql_stmt_bind_param.
-
- The two above members are mandatory for any kind of bind.
-
- buffer_length - the length of the buffer. You don't have to set
- it for any fixed length buffer: float, double,
- int, etc. It must be set however for variable-length
- types, such as BLOBs or STRINGs.
-
- length - On input: in case when lengths of input values
- are different for each execute, you can set this to
- point at a variable containining value length. This
- way the value length can be different in each execute.
- If length is not NULL, buffer_length is not used.
- Note, length can even point at buffer_length if
- you keep bind structures around while fetching:
- this way you can change buffer_length before
- each execution, everything will work ok.
- On output: if length is set, mysql_stmt_fetch will
- write column length into it.
-
- is_null - On input: points to a boolean variable that should
- be set to TRUE for NULL values.
- This member is useful only if your data may be
- NULL in some but not all cases.
- If your data is never NULL, is_null should be set to 0.
- If your data is always NULL, set buffer_type
- to MYSQL_TYPE_NULL, and is_null will not be used.
-
- is_unsigned - On input: used to signify that values provided for one
- of numeric types are unsigned.
- On output describes signedness of the output buffer.
- If, taking into account is_unsigned flag, column data
- is out of range of the output buffer, data for this column
- is regarded truncated. Note that this has no correspondence
- to the sign of result set column, if you need to find it out
- use mysql_stmt_result_metadata.
- error - where to write a truncation error if it is present.
- possible error value is:
- 0 no truncation
- 1 value is out of range or buffer is too small
-
- Please note that MYSQL_BIND also has internals members.
