Hi x-perts

Here is a simple SQL string:

It obviously returns an error, when a text string contains a quotation mark itself (like dog's)

How can I fox this?

Thanks
SQL = "INSERT INTO Betas (" & strFields & ") VALUES (" & strBetas & ")"
 
strFields = "[field1],[field2]"
 
strBetas = firstNumber & "'" & textValue & "'"
 
textValue = "dog's"

Aneesh is correct, but you just in case you didn't already notice, you will need to have a comma in strBetas.
SQL = "INSERT INTO Betas (" & strFields & ") VALUES (" & strBetas & ")"
 
strFields = "[field1],[field2]"
 
strBetas = firstNumber & ",'" & textValue & "'"
 
textValue = "dog''s"

thank you, but it doesn't work

1) coma is just a typo here (not in my actual code)
2) i cannot modify the dog's string, because it is taken as a field value from another table

is there a function to escape quotes like in php?
