They are easy to understand but sometimes we get bit of confused while actually implementing them. Stack Exchange network consists of 1QA communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. If substring _length is less than then Oracle returns null. CHAR, VARCHAR NCHAR, NVARCHAR CLOB, or NCLOB.

Both position and substring _length must be of datatype NUMBER, or any datatype that can be implicitly converted to NUMBER, and must resolve to an integer.

Summary: in this tutorial, you will learn how to use the SQL SUBSTRING function to extract a substring from a string.

Introduction to the SQL SUBSTRING function.

In Oracle, SUBSTR function returns the substring from a string starting from the specified position and having the specified length (or until the end of the string , by default). In SQL Server, you can use SUBSTRING function, but it does not allow you to specify a negative start position, and the substring length must be specified. The substring is the portion of the object that starts at character position pos and spans len characters (or until the end of the string , whichever comes first). Parameters pos Position of the first character to be copied as a substring. If this is equal to the string length, the function returns an empty string.

This article explains the functionality and uses of the LEFT, RIGHT, SUBSTRING and CHARINDEX functions in SQL. This article will leave you with sound knowledge and understanding that you can take away and questions will be asked no more. The SUBSTR function returns a substring of a string.

The functions vary in how they determine the position of the substring to return. I get the first name out of a string like this with sql plus in oracle.

Remember that not all database systems use the same name for SQL server string functions. I am using sql loader to load the data from text file to oracle table.

I have columns in the input data, which are of more size than their corresponding destination table column sizes. SUBSTR ( string ,pos,len) Returns the substring of string which begins at pos and is len characters long. If pos is negative, pos is counted from the end of string. The first position in string is not 0. TRANSLATE( string ,fromlist,tolist) Returns string with each character in the fromlist replaced with the corresponding character in the tolist.
