Is VARCHAR faster than text?
Some Differences Between VARCHAR and TEXT A VARCHAR can be part of an index whereas a TEXT field requires you to specify a prefix length, which can be part of an index. VARCHAR is stored inline with the table (at least for the MyISAM storage engine), making it potentially faster when the size is reasonable.
Is text slower than VARCHAR?
Short answer: No practical, performance, or storage, difference. Long answer: There is essentially no difference (in MySQL) between VARCHAR(3000) (or any other large limit) and TEXT .
What is text () in MySQL?
TEXT is the family of column type intended as high-capacity character storage. The actual TEXT column type is of four types-TINYTEXT, TEXT, MEDIUMTEXT and LONGTEXT. The four TEXT types are very similar to each other; the only difference is the maximum amount of data each can store.
Which is better varchar or text in MySQL?
Some Differences Between VARCHAR and TEXT The VAR in VARCHAR means that you can set the max size to anything between 1 and 65,535. TEXT fields have a fixed max size of 65,535 characters.

What is the maximum length of the text field?
The maximum length of a text message is 160 characters as long as you use standard 7 bit characters. Once you use a character that is not in the 7 bit encoding list, your maximum number of characters in a text message drops to 70.
How to switch from varchar to mediumtext in MySQL?
Regarding the automatic switching from VARCHAR to MEDIUMTEXT, note that a MySQL row can be only 65535 bytes (not counting BLOB/TEXT columns). If you try to change a column that would result a the total row size to exceed that limit, MySQL automatically prevents that situation by turning it into a MEDIUMTEXT.
When to use long text in a field?
The underlying database column for the plain text field type is defined by it’s Max Length setting under it’s field settings. If you set that to something crazy high (like greater than 4294967295), it should use Long Text.
Do you need to change varchar to LongText?
If 20,000 characters is enough, you should change content to VARCHAR (20000). If you need any more, you should use MEDIUMTEXT (LONG VARCHAR). Basically, even if you have changed field type and field size, failure will not occur. However, surely the performance will be degraded.
