Error Converting Data Type Nvarchar To Int.
a problem where running this SQL query: UPDATE tblBenchmarkData SET OriginalValue = DataValue, OriginalUnitID = DataUnitID, DataValue = CAST(DataValue AS float) * 1.335 WHERE FieldDataSetID = '6956beeb-a1e7-47f2-96db-0044746ad6d5' AND ZEGCodeID IN (SELECT ZEGCodeID FROM tblZEGCode WHERE(ZEGCode = 'C004') OR (LEFT(ZEGParentCode, 4) = 'C004')) Results in the following error: Msg 8114, Level 16, State 5, Line 1 Error converting data type nvarchar to float. The really odd thing is, if I change the UPDATE error converting data type nvarchar to datetime. to SELECT to inspect the values that are retrieved are numerical values: SELECT DataValue FROM tblBenchmarkData WHERE FieldDataSetID = '6956beeb-a1e7-47f2-96db-0044746ad6d5' AND ZEGCodeID IN (SELECT ZEGCodeID FROM tblZEGCode WHERE(ZEGCode = 'C004') OR (LEFT(ZEGParentCode, 4) = 'C004')) Here are the results: DataValue 2285260 1205310 Would like to use TRY_PARSE or something like that; however, we are running on SQL Server 2008 rather than SQL Server 2012. Does anyone have any suggestions?

Something like: SET DataValue = CASE WHEN ISNUMERIC(DataValue)=1 THEN CAST(DataValue AS float) * 1.335 ELSE 0 END share|improve this answer edited Feb 3 '12 at 23:27 answered Feb 3 '12 at 23:17 csm8118 1,143711 when isnumeric(datavalue) = 1, otherwise will not compile. –GSerg Feb 3 '12 at 23:20 @GSerg, thanks! –csm8118 Feb 3 '12 at 23:27 Thanks, works great! –user89861 Feb 6 '12 at 17:57 works and works. –Teoman shipahi Mar 4 '14 at 20:01 add a comment

We have two tables (and trust me I have nothing to do with these tables). Both tables have a column called eventId. However, in one table, data http://stackoverflow.com/questions/26765604/error-unable-to-convert-data-type-nvarchar-to-float type for eventId is float and in the other table, it is nvarchar. We are selecting from table1 where eventI is defined as float and saving that Id into table2 where eventId is defined as nvarchar(50). As a result of descrepancy in data types, we are getting error converting datatype nvarchar to float. Without fooling around with the database, I would like to cast the eventId to get rid of this error. Any ideas what I am doing wrong with the code below?

There are two ways to go about solving this: Convert your float to nvarchar, rather than the other way around - This conversion will always su

I nvarchar to have read in a table of data into a temporary table (#Temp_Results) and need to change the format of various columns before moving the data to the end table. What Im trying to do below is take a column (Oil2) that is an nvarchar and convert it to a tinyint and put the result into a new column (Oil4) then drop Oil2 - I realise I will loose decimal places but thats not a problem. The CASE statement is designed to capture error converting data anything that is not a number, seeing as the original datatype is nvarchar there could be anything in there and I'm only interested in the numbers. However when I run the code I get 'Error converting data type nvarchar to float' pointing towards the 'UPDATE' line of code and I cant figure out how to get round it. Can any of you guys spot my rookie mistake? ALTER TABLE tempdb..#Temp_Results /*Add new column with datatype of tinyint*/ ADD Oil4 tinyint GO UPDATE tempdb..#Temp_Results SET tempdb..#Temp_Results.Oil4 = CASE WHEN ISNUMERIC(tempdb..#Temp_Results.Oil2)=1 THEN CAST(ROUND(CAST(tempdb..#Temp_H_Results.Oil2 as float), 0) AS tinyint) ELSE NULL END ALTER TABLE tempdb..#Temp_H_Results /*Drop redundant column of data in wrong (nvarchar) format*/ DROP COLUMN Oil2 Go sql sql-server share|improve this question edited Apr 17 '14 at 10:43 marc_s 452k938641029 asked Apr 17 '14 at 10:26 Weevilofdoom 112 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote Try casting to Decimal in stead of float CONVERT(varchar(28), cast(tempdb..#Temp_H_Results.Oil2 as decimal(28,0))) share|improve this answer answered Apr 17 '14 at 10:36 divan 192 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

Thursday, June 27, 2013 7:15 PM Reply | Quote All replies 0 Sign in to vote Your query involves implicit conversion, which is plainly evident from the error message. So the question is which column(s) or expressions in your query are performing that conversion. Most likely it is File_NBR - so what are the definitions of this column in the two tables? Are vw_SBC_RESULTS and vw_SBC_Employee_Info tables - or views? If either is a view, then the problem may be with the query that defines the view (or your usage). I'll also point out that you intentionally performed a full
