![]() ![]() In this result set, the value came through as follows:Īha! This explained why SQL Server could convert the value to numeric, because of the scientific notation used when the values are very large or very small. I then ran another query that returned the rows, where the value was greater than 9.45, and ordered the results. This showed that the query stopped at the value 9.45. I ran a quick query, ordering the column in ASCENDING order, while running the original offending query that failed. In order to resolve the conversion error, you just need to remove the comma (,) from the varchar value that you want to convert to numeric. I knew that something was triggering the CONVERT instruction to go wrong. It’s not because you can’t convert that type to the new type. ISNUMERIC returned all of the rows as TRUE, and that confused me. If you’re getting SQL Server error Msg 8114 that reads something like Error converting data type varchar to numeric, it’s probably because you’re trying to perform a data type conversion that fails due to the value not being able to be converted to the destination type. However, on this occasion, using ISNUMERIC failed to identify any columns as being non-numeric. Then, I could identify the value, and then I could replace or exclude it, as required. ![]() Normally, I’d use ISNUMERIC to identify the rows that fail to have a value in that column that could be converted to a number. The error message is below, and it’s usually fairly easy to sort:Įrror converting data type varchar to numeric I noted that one of the columns failed to convert VARCHAR to DECIMAL. The data was all presented in string format initially (not my data, not my monkeys, not my circus), and I wanted to correct the data types before the data got into Power BI. check if all MP.PHONENUMBER can be converted to numeric or not. I am writing some SQL to form the basis of views to pull data from a Microsoft SQL Server source into Azure SQL Database, and then the data would go to Power BI. Query is trying to convert varchar which is not possible to convert to numeric. ![]()
