Sets a double precision floating point parameter.
Only the SQL data types REAL and DOUBLE PRECISION may be set using this call.
This routine may allocate additional memory to hold the parameter value, along with future output parameters and result set columns. This memory is freed when it is no longer needed, no later than when MimerEndStatement is called. This memory is also freed after a call to MimerExecute and MimerCloseCursor if there were no output parameters or result set columns.
Parameters
MimerStatement statementhandle,
int16_t param_no,
double value)
|
statementhandle |
in |
