The column is AMOUNT and it is stored as NVARCHAR(300),null.

ISNUMERIC returns 1 for some characters that are not numbers, such as plus (+), minus (-), and valid currency symbols such as the dollar sign ($). For a complete list of currency symbols, see money and smallmoney select isnumeric('+')---1 select isnumeric('$')---1 so try to add to avoid non numeric numbers messing with your ouput.. WHERE Reimbursement NOT LIKE '%[^0-9]%' If you are on SQLServer 2012,you could try using TRY_Convert which outputs null for conversion failures..

Use caution when Using CONVERT() with CASE or IF functions in Transact SQL (T-SQL) Provided by: FMS Development Team There are many articles available that cover the how-to's for using CONVERT() properly, however there is one that has very sparse coverage: Using CONVERT() with CASE or IF functions in Transact SQL (T-SQL) and what the expected results will be. For a stored procedure I had a requirement that if the value was a number, it needed to show 2 decimal places, and if it was not a number, return the original value. Of course it was all originally stored in the client table as nvarchar(50). So I decided that using a Case statement was the most ideal. However, I continua
| Related Tips: More > Data Types Problem We've been importing data into VARCHAR columns to verify valid character types before moving into our final destination table and we ran across some decimal values that wouldn't CAST or CONVERT even though they appeared to be decimal values (other decimal values from the same source converted without errors). We received the message "Error converting data type varchar to numeric" and even when we tried to import them as numbers they also failed. In addition, all values failed the ISNUMERIC function even though the values look numeric (like 1.00) and when we copy these values into Google Spreadsheets and run functions on them, we get numerical answers. How can we load these problem values? Solution Here is an example of the issue I was facing. In the below screenshot the data looks correct, but when I checked to make sure the values were numeric using a CAST function I got the following error message. Here are some of the things I noticed: They appear as numerical characters, yet don't convert.If we copy the values directly and do a direct SELECT CAST('1.00000' AS DECIMAL(22,8)), they convert without error.If they come with extra spaces, no trimming function works to remove the error. We seldom stumble on these types of data, but they can create encumbrances for developers, so it's good to know a work-around when transforming these VARCHARs into numerical data points. What differs about these data, compared to other times when facing issues with converting numerical VARCHARs to numerical data points is that all of them will fail the ISNUMERIC (for verifying), CAST, CONVERT, TRY_CONVERT and TRY_PARSE functions (the latter two returning NULLs). In other cases, when converting VARCHARs to numerical data points, we can use these other functions to solve the problem. In the below five examples, we expect to receive the error "Error converting data type varchar to numeric" on three of these due to characters that aren't convertible to decimals. We would not, however, expect to get this error on the second value (1.000000), yet these data will be formatted this way, which is why developers can become confused as to why clear decimal values aren't converting. SELECT CAST('Dog' AS DECIMAL(22,8)) SELECT CAST('1.000000' AS DECIMAL(22,8)) SELECT CAST('$1.00' AS DECIMAL(22,8)) SELECT CAST('765e1' AS DECIMAL(22,8
