Shows how to get an enum’s int value in different scenarios 1) Cast to int 2) With Convert.ToInt32() and 3) With GetTypeCode() and Convert. ![]() Mysql> Insert into marks(id, name, result) values(102,'Yashraj','Fail') In MySQL there are three main data types: string, numeric, and. See Section 13.1.20.7, Silent Column Specification Changes. In some cases, MySQL may change a string column to a type different from that given in a CREATE TABLE or ALTER TABLE statement. The data type is a guideline for SQL to understand what type of data is expected inside of each column, and it also identifies how SQL will interact with the stored data. The string data types are CHAR, VARCHAR, BINARY, VARBINARY, BLOB, TEXT, ENUM, and SET. mysql> Insert into marks(id, name, result) values(101,'Aarav','Pass') How can we create and use ENUM columns in MySQL - For creating an ENUM column, the enumeration value must be a quoted string literals. An SQL developer must decide what type of data that will be stored inside each column when creating a table. The value cannot be the error value (that is, 0 or the empty string). An ENUM is a string object with a value chosen from a list of permitted values that are enumerated explicitly in the column specification at table creation time. The query above will create a table named marks with an ENUM field. An ENUM value must be one of those listed in the column definition, or the internal numeric equivalent thereof. Then to create/update the enums, right click on 1 or more files and 'Run Custom Tool' (we don't have auto update yet). The ENUM data type in MySQL is a string object. The file contents are always the same single line: < include file'.\EnumGenerator.ttinclude' >.Example:įollowing is an example of creating a table with ENUM column − mysql> Create table marks(id int Primary key NOT NULL, Name Varchar(255) NOT NULL, Result ENUM('Pass', 'Fail') NOT NULL) For each enum type, create a file whose name is . datadir is /var/lib/mysql table is mydb.mytb enum column called is called enumcol engine is MyISAM Here is a death-defying crack at it: CREATE TABLE mydb.mybt LIKE mydb.mytb ALTER TABLE mydb. The parameters used in the above-mentioned syntaxes are as follows : enumname: Name of the enumerated data type. In the above syntax, we have three enumeration values. This is due to a change in 5.6.4 that permits these types to have a fractional part, which requires from 0 to 3 bytes. We can create ENUM columns in MySQL with the help of the following syntax − CREATE TABLE table_name( Detailed information about how to use the auxiliary/admin/mysql/mysqlenum metasploit module (MySQL Enumeration Module) with examples and msfconsole usage snippets. For TIME, DATETIME, and TIMESTAMP columns, the storage required for tables created before MySQL 5.6.4 differs from tables created from 5.6.4 on. For creating an ENUM column, the enumeration value must be a quoted string literals.
