Code language: SQL (Structured Query Language) (sql) In this syntax: target_type is the target data type to which you wan to convert the expression. The following example defines a variable of type varchar(10), assigns an integer value to the variable, then selects a concatenation of the variable with a string. An integer expression that specifies how the CONVERT function will translate expression. SQL Server supports the date format, in Arabic style, with the Kuwaiti algorithm. If you just hate all this talk of precisions and scales, and just want SQL server to perform all calculations in good old double precision floating point arithmetics from some point on, you can force that, too: or you place a decimal point in your value you are dividing by: Also _ inserting an int into a temp_table with like decimal(10,3) _ works ok. This example calculates a single column computation (Computed) by dividing the total year-to-date sales (SalesYTD) by the commission percentage (CommissionPCT). When you don't specify a length, SQL Server This example uses the AdventureWorksDW2019 database. If the variant contains a fixed-point or a floating point numeric For more bad row will cause the entire query to fail: To deal with this, you might be tempted to use the ISNUMERIC function. Therefore, we can adjust our example as follows to achieve the same result: Its important to remember to adjust the precision as required: If the precision argument isnt large enough, an error occurs: The CONVERT() function does the same thing as CAST(), except with a slightly different syntax: Another option is to use an arithmetic operator, such as a multiplication operator: In this example, we multiply the integer by 1.00. 1 Conversion of float values that use scientific notation to decimal or numeric is restricted to values of precision 17 digits only.
