TSQL SettingsThe default value is 1 (TRACE active).5.3 CASEINSCOMPAREThe CASEINSCOMPARE setting specifies non-case-sensitive equality comparisons, such as 'A'='a'. If this flag is set, thecomparison operators = and operate without regard to case in most contexts. However, there are a few contexts wheresuch insensitivity does not apply:• Where a comparison is the ON condition for a JOIN.• Where either operand is a subquery.These exceptions exist because Caché SQL does not accept the %SQLUPPER operator in these contexts.You can activate (=1) or deactivate (=0) CASEINSCOMPARE systemwide using the following Caché ObjectScript command:SET ^%sys("tsql","CASEINSCOMPARE")=15.4 QUOTED_IDENTIFIERThe QUOTED_IDENTIFIER configuration option allows you to select whether quoted identifiers are supported.
