When you convert data types that differ in decimal places, SQL Server will sometimes return a truncated result value, and at other times it will return a rounded value. In our example, we converted an integer (12) to a decimal value (12.00). as number, SELECT REPLACE((CONVERT(nvarchar(20), 5634.6334)),'. This is an approximate data type. You must manually update this data to match style 121. If you dont need to return the value in a certain format, use CAST(). displays might not unambiguously indicate which data conversions Snowflake coerced. For example, from a VARIANT containing false to FALSE. For a money or smallmoney expression, style can have one of the values shown in the following table. For example, the following COALESCE The SQL format model used to parse the input expr and return.

This number is subtracted from p to determine the maximum number of digits to the left of the decimal point. The minimum year value for datetime is 1753, while the minimum year value is 0001 for date and datetime2. Under compatibility level 110 and higher, the CAST and CONVERT operations on the time and datetime2 data types always have 121 as the default style. Always 8 digits. Integer constants greater than 2,147,483,647 are converted to the decimal data type, not the bigint data type. 9 Use the optional time zone indicator Z to make it easier to map XML datetime values that have time zone information to SQL Server datetime values that have no time zone. increase scale might fail.
