Unique Constraints in MySQL || MySQL Tutorial Series || Code With Neha

MySQL UNIQUE Constraint A UNIQUE constraint in MySQL ensures that all values in a column or a set of columns are distinct from one another. This constraint is used to prevent duplicate entries in a column or combination of columns, maintaining data integrity. Both the UNIQUE and PRIMARY KEY constraints provide a guarantee for uniqueness for a column or set of columns. A PRIMARY KEY constraint automatically has a UNIQUE constraint. However, you can have many UNIQUE constraints per table, but only one PRIMARY KEY constraint per table. SYNTAX:- UNIQUE Constraint on CREATE TABLE CREATE TABLE table_name ( ৫ column_name data_type UNIQUE, ... ); Or CREATE TABLE table_name ( column_name 1 data_type , column_name 2 data_type , ..... Unique (column_name) ); that's all for today Hope you all will get some help from this video If it's so then don't forget to subscribe my channel Code with Neha and press the Bell Icon for Regular Updates See you in the next video till then Stay Safe Stay Happy #uniqueconstraints #uniqueconstraintsinmysql #uniqueconstraintsinsql #mysqluniqueconstraint #sqluniqueconstraint #MySQLuniqueconstraint #SQLuniqueconstraint #constraintsinmysql #mysqltutorial #mysql #mysqlcourse #constraintsinmysql #constraintsinmysql #mysqlconstraints #mysqltableconstraints #tableconstraintsinmysql #mysqltableconstraintswithexample #mysqltableconstraintstutorial #whatistableconstraintsinmysql #tableconstraintsexplainedwithexample #sqltableconstraints #sqltableconstraintstutorial #tableconstraintsinsql #mysqltutorialforbeginners #mysql #mysqltutorial #mysqltutorialforbeginners #MySQL #MySQLTutorial #MySQLTutorialforbeginners
