classmethod clearSQLStatements(ns As %String = "", clearErrs As %Integer = 0, returnType As %Integer = 0, ByRef ptInfo As %ArrayOfObjects) as %Status [ Language = objectscript, SQLProc = UtilSQLStatements_clearSQLStatements ]

------------------------------------------------------------------------------- Method: clearSQLStatements Replaces: ClearStatements (%SYS.PTools.SQLUtilities) [DEPRECATED] Status: New Method to replicate Backward-Compatible Method it 'Replaces' Purpose: Delete all of the data stored in the '%SYS.PTools.UtilSQLStatements' class, based on the specified parameters... Invocation: This method can be invoked in the following ways: ObjectScript: ##class(%SYS.PTools.UtilSQLStatements).clearSQLStatements(...) SQL: CALL %SYS_PTools.UtilSQLStatements_clearSQLStatements(...) SELECT %SYS_PTools.UtilSQLStatements_clearSQLStatements(...) NOTE: This 'SqlProc' method can be invoked with either the CALL-interface or the SELECT-interface. Both interfaces execute the method: the CALL-interface does not return any resulting value, while the SELECT-interface does. Examples: The following examples shows the use of this method: #1 Delete all of the data stored in the '%SYS.PTools.UtilSQLStatements' class in the current namespace: set status=##class(%SYS.PTools.UtilSQLStatements).clearSQLStatements() Data Storage: ^%sqlcq($NAMESPACE,"PTools","util","SQLStmts") Parameters: ns - The namespace in which to clear SQL Index/Analysis Statstics [DEFAULT: Current Namespace] clearErrs - 0 = Don't delete the 'PTools' Application Errors 1 = Delete all of the 'PTools' Application Errors [DEFAULT: 0] returnType - 0 = Return a %Status code of either $$$OK or $$$ERROR() 1 = Return the number of Stats rows deleted from the following class: %SYS.PTools.UtilSQLStatements [DEFAULT: 0] ptInfo - A Pass By Reference information array that returns detailed information to the user in the following format: ptInfo(category,variable)=value OR $LB(val1,...,valn) Where category = { "cnt" | "curr" | "term" | ... } variable = A var corresponding to the given 'category' Example: ptInfo("cnt","clearSQLStatements")=The number of rows deleted via this method RETURN Value: Based on the value of the 'returnType' parameter, return one of the following: 0: Return a %Status code of either $$$OK or $$$ERROR() 1: Return the number of Stats rows deleted from the following class; Otherwise, return an error message if an error occurred: %SYS.PTools.UtilSQLStatements -------------------------------------------------------------------------------
