Add Column
The addcolumn
method allows you to add one or more columns to an existing table.
Usage
To add columns, use the addcolumn
key inside an altertable
definition. For each column you want to add, specify its properties just as you would in a createtable
definition.
{
"_id": "1.1.0",
"altertable": {
"users": {
"addcolumn": {
"email": {
"type": "VARCHAR",
"length": 255,
"unique": true,
"null": false
},
"created_at": {
"type": "DATETIME",
"default": "CURRENT_TIMESTAMP"
}
}
}
}
}
In this example, two new columns, email
and created_at
, are added to the users
table.
