Use this function to create an ESQL expression object that represents the statement specified by the statement argument, by using the syntax defined for the Compute node.
CciSqlExpression* cniSqlCreateStatement(
int* returnCode,
CciNode* nodeObject,
CciChar* dataSourceName,
CciSqlTransaction transaction,
CciChar* statement);
If successful, the address of the SQL expression object is returned. If an error occurs, zero (CCI_NULL_ADDR) is returned, and the returnCode parameter indicates the reason for the error.
