INT – A usual-size integer. The signed assortment is -2147483648 to 2147483647.
BIGINT – A pretty large integer.
Some other less frequent variety possibilities consist of:
FLOAT- A floating-stage range.
DOUBLE – A double-precision floating-stage selection.
DECIMAL – A packed correct preset-place range.
If the area is to be applied to shop text or equally text and quantities blended, in this article are some possibilities:
VARCHAR is for different people and can be up to 255 characters in length.
Text is a column with a highest duration of 65,535 characters – simple to search.
