i am taking input of sql query (for validation of field value against values retrieved by executing sql query) from admin user which will be stored in database and later i will executing sql query corresponding to field.Before inserting sql query in database i want to validate its syntax in java code.

Fields         Sql Query

stateCode      select statecode from states
district code  select district code from districts

Answer 1

Create a PreparedStatement with the query string; if this works, the query string is ok (but nothing is executed yet)

Answer 2

dont think there is any (easy) way to validate sql

Sql syntax is complex and allows for alot of different ways to enter a statement.

Think you best shot would be to just execute the sql statent and if you have a SQl exception see if its a bad syntax thats causing it.

you can prepend some sql to avoid from actually executing the query

in sybase it would be SET NOEXEC ON
