I'm trying to determine the best way to truncate or drop extra decimal places in SQL without rounding. For example: declare @value decimal(18,2) set @value = 123.456. This will automatically round @value to be 123.46, which is good in most cases. However, for this project, I don't need that.
V$SQL lists statistics on shared SQL areas without the GROUP BY clause and contains one row for each child of the original SQL text entered. Statistics displayed in V$SQL are normally updated at the end of query execution. However, for long running queries, they are updated every 5 seconds.
V$SQL_BIND_DATA describes, for each distinct bind variable in each cursor owned by the session querying this view: Actual bind data, if the bind variable is user defined. The underlying literal, if the CURSOR_SHARING parameter is set to FORCE and the bind variable is system generated.
STR( [Value],[Total Number of Didgits],[Decimal Places]) The correct calculation of [Total Number of Didgits] should be something like: LEN(CAST(ROUND([Value], 0) AS INT)) + [Decimal Places] + 1 /* + 1 for the decimal point itself */ this will get the number of digits before the decimal place. E.g.
V$SQL_BIND_CAPTURE displays information on bind variables used by SQL cursors. Each row in the view contains information for one bind variable defined in a cursor. This includes:
If you’d like to round a floating-point number to a specific number of decimal places in SQL, use the ROUND() function. The first argument of this function is the column whose values you want to round; the second argument is optional and denotes the number of places to which you want to round.
7 Αυγ 2015 · On SQL Server, you can specify: SELECT * FROM Table WHERE Value <> ROUND(Value,4,1); For an ANSI method, you can use: SELECT * FROM Table WHERE Value <> CAST(Value*100000.0 AS INT) / 100000.0; Although this method might cause an overflow if you're working with large numbers.
