Class: SYS.PTools.UtilSQLStatements Replaces: <class>SYS.PTools.SQLUtilities</class> [DEPRECATED] Purpose:
This class is used to store the SQL Statement details collected from the following Locations within InterSystems IRIS for Index Analysis, Performance Optimizations, and Additional Processing:

  • cached queries
  • Class Methods
  • Class Queries
  • MAC Routines

The following Methods and Queries, defined in the abstract interface class <class>SYS.PTools.UtilSQLAnalysis</class>, are used to collect, analyze, and optimize the SQL Statements in this class:

Method: clearSQLStatements Replaces: ClearStatements (<class>SYS.PTools.SQLUtilities</class>) [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
