![]() ![]() 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. I'm not sure why the date parameters in the sp are set as varchars, I can only wonder if it's to be compatible with the mysql DB.SSIS Integration Runtime in Azure Data FactoryĮxplicitly converts an expression from one data type to a different data type. When I run the stored procedure in visual studio I have tried all the different ways of entering the values for the dates I can think of but I still get the error.
