![]() This example casts an integer to a numeric with a precision of seven and scale of three. This example casts an integer to a decimal with a scale of two. This example casts a three-character string to double-byte characters. This example casts an integer to a character string using the 1252 code page. This example casts a numeric value to an integer. For example, if you cast character data to a DT_STR data type using the 936 code page, you should set charcount to a value up to two times greater than the number of characters that you expect the data to contain if you cast character data using the UTF-8 code page, you should set charcount to a value up to four times greater.įor more information about the structure of date data types, see Integration Services Data Types. If sufficient storage is available in the column of the destination table, set the value of the charcount parameter to reflect the number of bytes that the multibyte code page requires. Casting from a DT_WSTR to a DT_STR with the same charcount value may cause truncation of the final characters in the converted string. If the code page is a multibyte character code page, the number of bytes and characters may differ. To convert a string to a date data type other than DT_DATE, see Integration Services Data Types. However, the date is in the ISO format of YYYY-MM-DD, regardless of whether the locale preference uses the ISO format. When a string is cast to a DT_DATE, or vice versa, the locale of the transformation is used. (DT_TEXT,1252) casts a value to the DT_TEXT data type using the 1252 code page. (DT_NUMERIC,10,3) casts a numeric value to the DT_NUMERIC data type using a precision of 10 and a scale of 3. ![]() (DT_DECIMAL,2) casts a numeric value to the DT_DECIMAL data type using a scale of 2. (DT_BYTES,50) casts 50 bytes to the DT_BYTES data type. (DT_WSTR,20) casts 20 byte pairs, or 20 Unicode characters, to the DT_WSTR data type. (DT_STR,30,1252) casts 30 bytes, or 30 single characters, to the DT_STR data type using the 1252 code page. The following table lists these data types and their parameters. The following diagram shows legal cast operations.Ĭasting to some data types requires parameters. For more information, see Integration Services Data Types. The cast operator can also function as a truncation operator. This function is available in the Free version, and works in every version of SQL Server starting with SQL Server 2005: SELECT SQL#.String_TryParseToDecimal('7.SSIS Integration Runtime in Azure Data FactoryĮxplicitly converts an expression from one data type to a different data type. And, there is a pre-done function that does this in the SQL# library (that I wrote) named String_TryParseToDecimal. I was hoping to find something more elegant than two REPLACE calls, but so far no such luck.Īlso, just to mention, while not a pure T-SQL solution, this can also be accomplished via SQLCLR. The FORMAT function, but the input type must be a numeric or date/time/datetime value (that and it was introduced in SQL Server 2012, so not applicable to SQL Server 2008 R2 or older).Īnd nothing else seemed to work. Looking at various format styles for CONVERT, but nothing applies here. ![]() Then convert the comma into a period / decimal and you are done: SELECT CONVERT(NUMERIC(10, 2),įor the sake of completeness, I should mention that I also tried: You don't need (or want) the thousands' separator when converting to NUMERIC, regardless if it is comma, period, or space, so just get rid of them first. ![]() The approach outlined in my answer below is only required if you are using SQL Server 2008 R2 or older.) ( If you are using SQL Server 2012 or newer, please see answer for a cleaner approach. ![]()
