![]() ![]() Here are some more examples of using the strict inequality. The operator returns a boolean result: true if the values are not equal false if the values are equal The strict inequality () operator is the negation of the strict equality () operator. I expect this to return results from Point (C) but with (D) in mind. We used the strict inequality () operator to check if two strings are not equal. WHERE ( 'Scheduled' or 'PreliminaryScheduled') WHERE CONCAT(,'-',) 'Scheduled-PreliminaryScheduled' Work Around - Or is this the actual way this has to be done? They both result in the same query plan (using OR), you. WHERE ( 'Scheduled' AND 'PreliminaryScheduled') Negate the condition you don't want records to meet using NOT: SELECT FROM temp WHERE NOT ( status 'Scheduled' AND fkStatus 'PreliminaryScheduled') Alternatively, use OR: SELECT FROM temp WHERE status <> 'Scheduled' OR fkStatus <> 'PreliminaryScheduled'.If expr is greater than or equal to min and expr is less than or equal to max, BETWEEN returns. We can use this to create an array on the fly, then see whether the value matches one of the values in the. NOT IN(), Whether a value is not within a set of values. ECMAScript 5 introduced an indexOf method on Array.prototype. SQL Not Equal is a comparison operator used to compare two not null operand values or an expression, if the left operand value is not equal to the right. indexOf() returns the value’s position, so we only have to make sure the result is different from -1 (which is what indexOf() returns if the value isn’t found). ![]() But for one check it’s a lot of typing and takes up a lot of space. Instead of repeating our search value/variable, we’re using JavaScript’s native () method to see if it exists in an array of values. Real world logic, I beleive this should work?. This approach would be helpful if we have to handle for multiple classifications of fruits. WHERE ( = 'Scheduled' AND = 'PreliminaryScheduled') Note: While the code samples cover multiple languages, the text explaining the samples refers to the Web method names. I want to write an if/else statement that tests if the value of a text input does NOT equal. Brings back what I DO NOT want, these are the items that I want to exclude. boolean-logicconditional-statementsequalsif-statementjavascript. (N'Scheduled', N'PreliminaryScheduled', GETDATE()), (N'Scheduled', N'PreliminaryScheduled', ''), (N'Cancelled', N'PreliminaryScheduled', ''), (N'Complete', N'PreliminaryScheduled', GETDATE()), (N'Scheduled', N'Other', '') I have a work around also but I would like to know if there is a proper/better way of doing this task. I know I can exclude these by doing a where not exists but in the actual database this would be a big table and I would prefer not to double query this. I hope this makes sense, please see the script below, I have included a very basic temp table created with examples of what I am trying to achieve, I havea workaround by using a CONCAT but I don't think this is the best solution? I am trying to work out how to pull back records where "Field A" and "Field B" cannot be a set combination.Įxample: Field A cannot equal "Scheduled" whilst Field B Equals "PreliminaryScheduled"īut I do want to see other records where Field A = "Scheduled" and Field B = "PreliminaryScheduled"
