Member Function Documentation

◆ debugInternal()

void KDbBinaryExpressionData::debugInternal ( QDebug  dbg,
KDb::ExpressionCallStack callStack 
) const
overrideprotectedvirtual

Sends information about this expression to debug output dbg (internal).

Reimplemented from KDbExpressionData.

Definition at line 294 of file KDbBinaryExpression.cpp.

◆ typeInternal()

KDbField::Type KDbBinaryExpressionData::typeInternal ( KDb::ExpressionCallStack callStack) const
overrideprotectedvirtual
Todo:
add general support, e.g. for "NULL AND (1 == 1)"; for now we only support constants because there's no evaluation and operations with NULL depend on whether we have TRUE or FALSE See https://www.postgresql.org/docs/9.4/static/functions-logical.html https://dev.mysql.com/doc/refman/5.0/en/logical-operators.html
Todo:
Any OR NULL may be also TRUE – but this needs support of fuzzy/multivalue types
Todo:
NULL OR Any may be also TRUE – but this needs support of fuzzy/multivalue types
Todo:
Any AND NULL may be also FALSE – but this needs support of fuzzy/multivalue types
Todo:
NULL AND Any may be also FALSE – but this needs support of fuzzy/multivalue types
Todo:
can be other Integer too
Todo:
can be other Integer too

Reimplemented from KDbExpressionData.

Definition at line 77 of file KDbBinaryExpression.cpp.

◆ validateInternal()

bool KDbBinaryExpressionData::validateInternal ( KDbParseInfo *  parseInfo,
KDb::ExpressionCallStack callStack 
)
overrideprotectedvirtual
Todo:
IMPORTANT: update type for query parameters
