Good answer, my 5!

Solution 4

And another variation is

SQL

SELECT ...
FROM   YourTable 
WHERE  1 = ISNUMERIC( SUBSTRING( FieldName, 1, 1))

However, If you need to find this kind of information in your query it may indicate that you are actually concatenating two separate data items inside a single field. So if that would be the case, then I'd suggest that you store each data in it's own field.

~~Good answer. +5~~
Sorry, but i need to re-vote. The query returns bad results, especially when the first sign is: ',,', '-'

Example to study:

CREATE TABLE #Names (FactoryName NVARCHAR(50) NULL)

INSERT INTO #Names (FactoryName)
VALUES ('-HIID SIIMSON')
INSERT INTO #Names (FactoryName)
VALUES ('-INGA')
INSERT INTO #Names (FactoryName)
VALUES (',,AMPHORA"')
INSERT INTO #Names (FactoryName)
VALUES ('"MP TRANS"')
INSERT INTO #Names (FactoryName)
VALUES ('.NET')
INSERT INTO #Names (FactoryName)
VALUES ('.K.')

SELECT DISTINCT [FactoryName]
FROM   #Names
WHERE  1 = ISNUMERIC(SUBSTRING(LTRIM([FactoryName]), 1, 1))

SELECT DISTINCT [FactoryName]
FROM   #Names
WHERE  [FactoryName] Like '[1234567890]%'

DROP TABLE #Names

Compare results ;)

That's correct, also for example + sign is considered as numeric. This is because decimal separators and + and - are considered as parts of a number. Depending on the requirements this may/may not be the desired result :)

rashidfarooq 10-May-12 14:21pm

SELECT DISTINCT [FactoryName]
FROM #Names
WHERE [FactoryName] Like '[1234567890]%'

This pattern doesn't work.

Could you give an example data?

Maciej Los 10-May-12 15:55pm

Please, copy all example code, starting from CREATE TABLE... and ending on DROP TABLE. I have MS SQL Server 2005 EE with + Management Studio and it works perfect.

Wendelius 10-May-12 16:24pm

Yes, the results are as expected. I must admit that I don't quite understand the point. As I mentioned, certain characters are interpreted as numeric with ISNUMERIC. Whether this is correct or not depends on the OP's requirements

Maciej Los 10-May-12 17:09pm

Exactly! ;)

Solution 3

Try this:

SQL

SELECT * FROM myTable WHERE myField LIKE '[0123456789]%'

The [0123456789] part says "any character in this set" and the % matches any text at all.
