json
"Create Table": {
"prefix": "createTable",
"body": [
"CREATE TABLE ${1:table_name} (",
"\t${2:column_name} ${3:data_type},",
"\t${4:column_name} ${5:data_type}",
");"
],
"description": "Create a SQL table"
}

Now, typing createTable in any SQL file will autogenerate the basic structure of a CREATE TABLE statement.

Error Handling and Debugging

Always check the output panel in VS Code for any error messages related to your SQL queries. These messages can provide crucial information to help you troubleshoot issues.
