| 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. | |
