Famous Quotes Database Sql Code Is Doing
70-357: Developing Mobile Apps.For those who haven't seen this, or don't really understand it, what the code is doing is replacing all of the single quotes (') with 2 single quotes (''). 70-348: Managing Projects and Portfolios with Microsoft PPM. 70-347: Enabling Office 365 Services.
You would write = 'O''Neil'. If it helps, think of putting O'Neil into a string. Note again there are 2 single quotes for each single quote we want to represent.
So '''''' actually represents ''.Why would we want to mess with this? Since T-SQL uses 's to delimit strings there has to be a way to put a single quote inside of the string. When you look at it try to ignore the outside quotes and see the inside quotes in pairs. Hopefully this also makes '''''' a little easier to understand.
We put 'O''Neil' and the compiler is happy, it understands that what you are trying to say is O'Neil.Sounds simple right? So let's try it out.PRINT sp_executesql output looks like this:Unclosed quotation mark after the character string ''.Now I hear someone muttering at the back of the class saying “I put in the two single quotes like you told me but it's still wrong!”And they would be right. The way this is handled is by using two single quotes. It's very similar to the problem of extra commas in a comma delimited file. Is it the string O'Neil? The string Neil with a mistaken 'O at the beginning? Or the string O with a mistaken Neil' at the end. If you are curious look it up in BOL.) For example the compiler is going to have a hard time understanding 'O'Neil'.
In case you have never tried it before this would be similar to dynamically creating dynamic SQL. Now for homework please fill in the following:EXEC sp_executesql you look closely this piece of code takes the previous example prints it out and then and runs it dynamically. What we need to be stored in is “PRINT 'O''Neil'”.Now everyone go back to the top, I'll wait.PRINT sp_executesql familiar? Now our output looks like this:Everyone follow? Good. So now the variable has “O'Neil” in it. ( SET = 'PRINT''' + + '''' ) But remember, when the value was stored into the variable the two single quotes ('') were translated into a single quote ('). That would be why the extra single quotes in the SET statement.
