![]() WHERE (first_name LIKE "A%") OR (last_name LIKE "K%") Query Example #5 SELECT stuent_id, First_name, Marks FROM customer Query Example #4 SELECT stuent_id, First_name, Marks FROM customer ![]() (this will fetch records of the student whose first_name ends with ‘t’ like Rohan, Raman, etc. Query Example #3 SELECT stuent_id, First_name, Marks FROM customer (this will fetch records of a student whose first_name’s 2 nd character is ‘a’ like A adit, R aghav, etc.) Query Example #2 SELECT stuent_id, First_name, Marks FROM customer ![]() (this will fetch records of students whose last_name’s 2 nd character from last is ‘a’ ) We will write some queries and see how it will fetch the record. (this will fetch records of student whose first_name’s 2 nd character from last is ‘a’ like Sohan ) Examples to Implement LIKE in MySQL (this will fetch records of a student whose first_name’s 2 nd character is ‘a’ like Aadit, Raghav, etc.)Įxample 5: SELECT stuent_id, First_name, Marks FROM student SELECT stuent_id, First_name, Marks FROM student (this will fetch records of a student whose first_name ends with ‘n’ like Rohan, Raman, etc. (this will fetch records of a student with an ‘a’ character in their first_name, like Sohan, Sakti, etc.)Įxample 3: SELECT stuent_id, First_name, Marks FROM student (here, it will fetch all records of the student whose first name starts with ‘A’, like Aseem, Abhishek, etc.)Įxample 2: SELECT stuent_id, First_name, Marks FROM student If we want to fetch records based on their names, then the LIKE operator will come into play.Įxample 1: SELECT stuent_id, First_name, Marks FROM student Let’s consider we have a student table containing the following attributes, (here we search for the field column_name in the table table_name where column_name’s records start with A) How LIKE work in MySQL? Underscore (_) matches only a single character in the database.īasic syntax: SELECT column_name FROM table_name.Percentage (%) matches strings of zero or more characters in the database.You will have to fix the environment(it is just a couple environment variable settings) provides two kinds of special characters for constructing our conditions to apply to strings. OH, and if you are using an oracle version prior to 12(I forget the EXACT version in 12 where they fixed it), and you find the problem is THERE, it might be an ENVIRONMENT problem. Then maybe try key points in between to find one that fails, and work back from there. If it is bad, the problem is with the source driver, or some source centric area. If it is right, the problem is with the target driver, or some target centric area. Check the target(just before the converter in the preview window). Your first task should be to run the process with a few of the offending records in preview mode. The HTML-codes are Ł and ł for Ł and ł, respectively.” In the LaTeX typesetting system Ł and ł may be typeset with the commands \L, respectively. ![]() “The Unicode codepoints for the letter are U+0142 for the lower case, and U+0141 for the capital. One good thing though, these are unicode, so it SHOULD be doable: With GRAPHIC characters, especially if they are the early microsoft/IBM ones, all bets might be off, and you may have to settle.In some cases, like some Microsoft installations, you must use the exact code page sometimes. ![]() In some cases, like older Oracle installations, the operating system environment containing such instances must be setup right.EVERYTHING must support it all the way… The input, processing, and output, as well as source and target.The default is often ASCII, and if you want to support unicode: The problem here is that unicode has a few problems, so it can’t be supported 100%, and everything and everyone support it a bit differently. Does that other ETL process work with the same database(what Oracle users might call a schema)? ![]()
