![]() ![]() This implies that you know the type of the enumeration when converting. You can convert from an integer using Enum.ToObject method. when they cross that border, things tend to get a bit messy. Other option like lookup tables can be considered if the scenario is more complex.Įnumerations are excellent when they are self contained in code. If on the other hand you have the need to support multiple language and external application access to your data you can start considering if enumeration are really the answer. You can use for this and methods for the conversion can probably be found by searching SO. What are the i18n needs for your application? If it only supports one language you can save the enumeration as text and create a helper method to convert from a description string. This will limit the possibility of the enumeration being stored in it's integer format because that value will have no meaning when present in a report unless the reports have custom logic. Is the enumeration column going to be used directly by other applications like for example reports. You can view EDUCBA’s recommended articles for more information.Some things you should take in consideration. We hope that this EDUCBA information on “MySQL ENUM” was beneficial to you. ![]() In the above insert, we could see that there are two rows the values which we inserted into the table for the column “Grade” are other than “Pass” and “Fail”. Insert into student_data values(10,'Harry','Fail') Insert into student_data values(9,'Mona','Pass') Insert into student_data values(8,'Haminton','Fail') ![]() Insert into student_data values(7,'Will','Pass') Insert into student_data values(6,'Malesha','No') Insert into student_data values(5,'So jioo','No') Insert into student_data values(4,'Hyung','Fail') Insert into student_data values(3,'Sam','Pass') Insert into student_data values(2,'Ram','Fail') Let us insert data into the table: – insert into student_data values(1,'Sai','Pass') Grade enum('pass','fail') / * - ENUM Data type column - * / Let us consider another example below and check the working of the ENUM. Select the items from the table: – Here, the values inserted that are other than ‘Y’ and ‘N’ are represented as NULL. Let us insert data into the table: – insert into student_sports_data values(1,'Sai','Y','Y','N','Y','Y','N','Y') Swimming enum('Y','N')/*- ENUM Datatypecolumn-*/ Table creation: – create table Student_Sports_data Let us consider a simple example of the same: – If we check the list of all users, the columns specified in the user table are mostly defined as an ENUM data type. ![]() Let us see where the ENUM is usually defined in MySQL. It has readable queries, which makes it a readable query and output.), which represent the string values because of which it has compact data storage. MySQL ENUM uses numeric indexes (1, 2, 3.Here the values for the “column_name1” and “column_name2” are one among the list specified. Let us see the syntax of how we create the column of ENUM datatype: – create tableĬolumn_name1 ENUM(value1, value2.),/ * - ENUM Data type column - * /Ĭolumn_name2 ENUM(value1, value2.),/ * - ENUM Data type column - * / In this session, we will learn about the ENUM data type with syntax along with the syntax: – ![]()
