Sorting Strings in SQL Server with T-SQL For example, “Abc1.2xy31b” and “Abc1.10xy31c” can be decomposed to the following strings (S1 means 1stS-string and N3 means the 3rdN-string) OriginalS1N1S2N2S3N3S4 Abc1.2xy31bAbc1.2xy31b Abc1.10xy31cAbc1.10xy31c When we compare these two...
You may recall that %[0-9]% means to return a match, if any position in the string is in the range of characters 0-9. For instance PATINDEX(‘SQL2005’, ‘%[0-9]%’) returns 4, since the numeral 2 is in the fourth position. Stated differently, the first character to match %...
the SET QUOTED_IDENTIFIER option must be set to ON. Otherwise, the operation will fail and the SQL Server will return an error with all SET options that violate the required values. The SET NUMERIC_ROUNDABORT setting is set at parse time, which means that the SET QUOTED_IDENTIFIER statement ...
When you have a numeric, the first number (p) is the total number of digits that can be stored. The second number (s) is how many of those digits are on the right of the decimal point. Numeric(5,5) means store 5 digits total, all 5 on the right of the decimal point. ...

When you declare a decimal(8, 7) on Sql Server, it means the following: A decimal with 8 digits, 7 of them being after the decimal point Something like, 1.234567, but not 12,34567 because out of the 8 digits, 7 of them must be on the right hand side of the decimal point. If ...
Be VERY aware that the definition of what is "numeric" encompasses a whole world of characters that you never imagined and that ISNUMERIC will allow many strange renditions of what "numeric" actually means that will blow up in your face. For example, what will ISNUMERIC return for th...
As of MySQL 8.0.17, theZEROFILLattribute is deprecated for numeric data types; you should expect support for it to be removed in a future version of MySQL. Consider using an alternative means of producing the effect of this attribute. For example, applications could use theLPAD()function to...
