sql server - T-SQL converting string into float -


in stored procedure on sql server, trying convert values varchar column float format. values varchar column numbers sign @ beginning , '.' before decimals.

examples: '+0000000000000044.09' or '-0000000000114995.61'

if try this: convert(float,mystring), doesn't work. have: error converting data type varchar float

please tell me if possible kind of conversion. or there way convert string sign , '.' float?

thank you, nello

as examples both work, i'd guess there's value somewhere in table that's causing problem. in recent versions of sql server (2012 onwards), try_convert function can useful tracking down kind of issue.

try_convert not throw exception on conversion failure, instead return null value, can figure out values causing problem this:

select * your_table try_convert(float, your_column_name) null

if rows returned, rows problem values can't converted float.
