SQL Query Fix

Hi All

Can you advise what wrong with my SQL query

Getting this error

ORA-00936: missing expression

00000 - "missing expression" Cause: *Action: Error at Line: 2 Column: 24 SELECT FROM DATA_NETWORK_AUDIT WHERE (nominated_party like '%Kier Group PLC%' or nominated_party like '%Kier%' or nominated_party like '%C&W Kier%' or SELECT LOWER('keir') from DATA_NETWORK_AUDIT;)

There seem to be a few issues:

  • there should be something being selected between the first SELECT and FROM
  • the parentheses seem misplaced (and perhaps not needed)
  • the purpose of the second "SELECT" is not clear, perhaps it's also not needed
  • LOWER('keir') would be the same thing as just 'keir', did you want a field reference?

Also, while it won't cause an error, it is not necessary to separately test for "like '%Kier Group PLC%'" or "like '%C&W Kier%'" because "like '%Kier%'" would cover both of those patterns by itself.

Can suggest how it should look

I'd need to know more about what the query is intended to do, it's not clear from this code.

So if you want all fields from each row and do a case-insensitive match on the name, you might use:

SELECT * FROM DATA_NETWORK_AUDIT WHERE LOWER(nominated_party) like '%kier%';

The "*" symbol is a shorthand that means "all columns".

Hi Steven

So I need to pull information from our backend SQL table

The name is Kier but there so many variables of the name

I was told to use lower in my query to get results regardless of the variables of the name

Thanks
