You can use charindex () and reverse () to get your desired results: declare @temp varchar (40) set @temp = 'BB10-1_X-4759-566549' select @temp, REVERSE (@temp) select REVERSE (substring (REVERSE (@temp),0,CHARINDEX ('-',REVERSE (@temp),0))) Give this a shot. It answers your first question of extracting from after the last - of the string SELECT name, SUBSTRING(name, 1, 1) AS Initial , SUBSTRING(name, 3, 2) AS ThirdAndFourthCharacters FROM sys.databases WHERE database_id < 5; Hier ist das Resultset. Here is the result set In Oracle, if the length is not specified, the substring is taken from the start position until the end of the string. In SQL Server, the length must be specified, and you can use LEN function to provide the length parameter The SUBSTRING function accepts three arguments: The source_string is the string from which you want to extract the substring. The position is the starting position where the substring begins. The first position of the string is one (1) Code language: SQL (Structured Query Language) (sql) The SUBSTRING() function returns a substring from the source_string starting at start_position with the substring_length length.. The following explains the meanings of the three arguments: source_string. The source_string is the source string from which you want to extract a substring.. start_position. The start_position is a positive.

You may use SUBSTRING to extract characters from the middle: SUBSTRING(field_name, starting position, ending position relative to the starting position) Let's create a third table called dbo.table_3. As you can see, the digits are now located in the middle of the strings: In order to get only the digits in the middle, you may run this query SUBSTRING includes spaces as a position within a string. So executing this query shows a window of the string that has been passed to it. If we had executed the query as SELECT SUBSTRING('HELLO WORLD',6,5) then the results would have shown WORL The SUBSTRING function in MySQL database starts counting from the end of string if you provide a negative number. However, the MS SQL Server's SUBSTRING function does not. The following example shows using the MySQL SUBSTRING function with a negative starting position

The following example shows how to return the second, third, and fourth characters of the string constant abcdef.

The SUBSTRING SQL function is very useful when you want to make sure that the string values returned from a query will be restricted to a certain length. So you're getting an idea of how the SQL SUBSTRING function works. The field that we want to act on, we start at which character, and we end at which characte The SQL SUBSTRING function cuts out and returns the specified number of characters from the string. SQL-function SUBSTRING can be used in Delphi applications working with queries to local SQL, but it is not supported when working with InterBase (IB) and Local InterBase Server (LIBS) tables. Below is the syntax of the SUBSTRING function, examples of its use in local SQL queries, and an alternative to return the same results for IB/LIBS tables

If substring_length is omitted, then Oracle returns all characters to the end of char. If substring_length is less than 1, then Oracle returns null. char can be any of the datatypes CHAR, VARCHAR2, NCHAR, NVARCHAR2, 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. The. One solution could be: SUBSTRING (Serial, 18, 38) And it always return the substring from 18 to the end of the string even if the string doesn't have a length of 38. sql-server t-sql sql-server-2016 substring If negative, the scanning starts from the end of the string. length - the length of characters to extract.

ID Name City Pincode Mobile; 1: Meera: Bombay. In the below examples, the first example demonstrates the use of the substr function which works exactly as the substring function in T-SQL. You can also use substring function, which takes the string, start position and end position as the arguments. You can use ranges for the start position and end position parameter

The PLSQL SUBSTR function is used for extracting a substring from a string. The SUBSTR function accepts three parameters which are input_string, start_position, length. SUBSTR calculates lengths using characters as defined by the input character set. SUBSTRB uses bytes instead of characters. Note: If position is 0, then it is treated as 1 Microsoft SQL Server. Is it possible to use substring and join? by Rhya. on (Substring(sm.CRS_CDE,0,9)) as 'Course', sm.CRS_COMP1 as 'Course Code', sm.CRS_COMP2 as 'Course_Number', sm.CRS_TITLE as 'Course_Title', CASE WHEN sm.FIXED_VAR_CREDIT = 'F' THEN sm.CREDIT_HRS end as 'Credit_hrs', CASE WHEN sm.FIXED_VAR_CREDIT = 'V' THEN sm.MIN_CREDIT_HRS ELSE 0 END as 'Credits_min', CASE WHEN sm.

If start_position is 0, then the SUBSTR function treats start_position as 1 (ie: the first position in the string). If start_position is a positive number, then the SUBSTR function starts from the beginning of the string. If start_position is a negative number, then the SUBSTR function starts from the end of the string and counts backwards SQL Server CHARINDEX() function is used to search the position of a substring inside an input string. Unlike SUBSTRING(), this function starts the search from a specified location and returns the position of the substring. If a substring is not found, it returns zero. CHARINDEX() function is used to perform case sensitive and case insensitive searches based on the collation specified in the query Extracting string after and before a Character/Pattern asaratsaga , 2017-01-06 (first published: 2015-11-09 ) Usually we see lof of codes flying around for this extraction.Most of them difficult.

The MSSQL SUBSTRING function does not provide this functionality. Also in MySQL if we don't pass any value for length argument it returns the substring from START position to the end of the string. Here is the Syntax and Examples of this function in MSSQL and MySQL. MS SQL Server Syntax SUBSTRING ( expression ,start , length ) WHERE . expressio Next, the string This is T-SQL code is assigned to the first @myvar string. Next, the SUBSTRING function is called. The SUBSTRING function starts at index 0 to obtain a new string. The string's index starts at 0, but if you use any value less than 1, the function starts at the beginning of the main string, which in this case is @myvar. The third parameter indicates how many characters.

Tip: Use SUBSTR to Remove the Last Character from any String in Oracle SQL This code snippet is great for removing trailing slashes or other characters from the end of a string. by Benjamin Brumm: Apr 11, 2017: Let's say you have a set of string values (such as values in a column) and you want to remove the last character. But, the string values are all different lengths. How can you do that. If the sum of position and length is greater than the number of characters of the string, the SUBSTRING function returns a substring starting from the position to the end of the string. For example, to get the MySQL from the MySQL SUBSTRING, you use the following statement Example of MySQL SUBSTRING() function extracts from the end The following MySQL statement returns the 5 number of characters from the 15th position from the end of the column pub_name instead of the beginning for those publishers who belong to the country 'USA' from the table publisher SUBSTRING returns a specified part of the input character string, beginning at the position that is specified by start. If length is omitted, then the SUBSTRING function returns all characters from start to the end of the input character string. The values of start and length must be numbers (not variables) and can be positive, negative, or zero

If string is a character string, the result of the function is a= character string represented in the code page of its first It is the most powerful way to use Regex in SQL. Regex does not use = and != to compare rather it uses these POSIX comparators: ~: Case-sensitive, compares two statements, returns true if the first string is contained in the second ~*: Case-insensitive, compares two statements, returns true if the first string is contained in the secon EndsWith () It is equivalent to '%string'. Before we start implement LINQ to SQL LIKE operator examples first we need to create a database with required tables and map those tables to LINQ to SQL file ( .dbml) if you don't know the process don't worry check this link create and map database tables to LINQ to SQL file (.dbml)
