Delphi: Paradox DB Field Name Issue (Spaces in field name)

I have a paradox table from a legacy system I need to run a single query on. The field names have spaces in them - i.e. "Street 1". When I try and formulate a query in delphi for only the "Street 1" field, I get an error - Invalid use of keyword. Token: 1, Line Number: 1

Delphi V7 - object pascal, standard Tquery object name query1.

I think you must use [ and ] instead of ":

SELECT customers.[Street 1] FROM customers WHERE ...

You normally need to quote the field name in this case. For example:

select * from t1 where "street 1" = 'test';

I tried this on a paradox 7 table and it worked. If that doesn't help, can you post the query you are trying to use? It would be easier to help with that info.

You need to prefix the string with the table name in the query.

For example: field name is 'Street 1', table is called customers the select is:

SELECT customers."Street 1" FROM customers WHERE ...

I only need the street information from the address details held in the customer table. I can get it to work fine if I do a SELECT * FROM customers, however this is a very large table and returns numerous results. If I do SELECT "Street 1" FROM customers, the output is "Street 1" in every record returned - i.e. it does not return the actual data. It must be something to do with the use of "

Thanks for your help
