Logical Operator Precedence (QUESTION) #1070
Description
Describe the question
I have a doubt about operator precedence
Indeed the following code
CCJSqlParserUtil.parseCondExpression("TYPE=1 or TYPE= 2 and OS=25", false);return OrExpression
Shouldn't this be
return AndExpression due to the higher precedence of And ?
To Reproduce
CCJSqlParserUtil.parseCondExpression("TYPE=1 or TYPE= 2 and OS=25", false);
System
