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

IMPORTANT: update type for query parameters
