SAParam::setParamDirType |
||
void setParamDirType( SAParamDirType_t eParamDirType );
Sets parameter's direction type (input, output, etc.).
Parameters
eParamDirType . Defines parameter's direction type. Can be one of the following SAParamDirType_t enum values:
- SA_ParamInput Input parameter.
- SA_ParamInputOutput Input/output parameter.
- SA_ParamOutput Output parameter.
- SA_ParamReturn Returning parameter.
Remarks
Usually you should not define parameter's direction type by yourself. The Library automatically detects parameter's direction type and implicitly creates an appropriate SAParam object. But not all of DBMS clients/servers provide complete parameters information. In that situation programmer need to describe parameter's direction type explicitly. See Server specific notes for details.

Sybase ASE server does not provide
information about parameter's direction type, that's why SQLAPI++
Library defines all parameters (except status result code) as input
(SA_ParamInput). If you have input-output parameters in the procedure
you have to call SAParam::setParamDirType method for
these parameters before command execution and set parameter's direction
type explicitly. There is no need to call this method for Sybase ASA because all parameters are detected correctly automatically (including the direction type). |
