Name

SPI_execute_plan_with_paramlist -- execute a statement prepared by SPI_prepare

Synopsis

int SPI_execute_plan_with_paramlist(SPIPlanPtr plan,
                                    ParamListInfo params,
                                    bool read_only,
                                    long count)

Description

Note: At present, this section is just taken from PostgreSQL documentation and is subject to revision for Postgres-XC.

SPI_execute_plan_with_paramlist executes a statement prepared by SPI_prepare. This function is equivalent to SPI_execute_plan except that information about the parameter values to be passed to the query is presented differently. The ParamListInfo representation can be convenient for passing down values that are already available in that format. It also supports use of dynamic parameter sets via hook functions specified in ParamListInfo.

Arguments

Return Value

Note: At present, this section is just taken from PostgreSQL documentation and is subject to revision for Postgres-XC.
