Custom Parameter Types

When passing a parameter to qb, it will infer the sql type to be used. If you pass a number, CF_SQL_NUMERIC will be used. If it is a date, CF_SQL_TIMESTAMP, and so forth. If you need more control, you can pass a struct with the parameters you would pass to cfqueryparam.

QueryBuilder
query.from( "users" )
    .where( "id", "=", { value = 18, cfsqltype = "CF_SQL_VARCHAR" } );

MySQL
SELECT *
FROM `users`
WHERE `id` = ?

This can be used when inserting or updating records as well.

QueryBuilder
query.table( "users" )
    .insert( {
        "id" = { value 1, cfsqltype = "CF_SQL_VARCHAR" },
        "age" = 18,
        "updatedDate" = { value = now(), cfsqltype = "CF_SQL_DATE" }
    } );

MySQL
INSERT INTO `users`
    (`id`, `age`, `updatedDate`)
VALUES
    (?, ?, ?)

Strict Date Detection

By default, qb will try to determine if a variable is a date using the built-in isDate function. This can have some interesting effects with different formatted strings. You can opt in to stricter date detection which will check the underlying Java class of the value to determine if the value is a date. This is more accurate, but does require you to specifically pass date instances instead of strings. For this reason, it is currently opt-in to not break existing applications. It is likely to become the default in the next major version of qb.

You can opt in to stricter date detection by setting strictDateDetection = true in your moduleSettings in config/ColdBox.cfc.

moduleSettings = {
    "qb": {
        "strictDateDetection": true
    }
};

Numeric SQL Type

By default, qb will use the CF_SQL_NUMERIC SQL type when it detects a numeric binding. You can specify your own default SQL type to use with numeric values using the numericSQLType setting in your moduleSettings in config/ColdBox.cfc.

moduleSettings = {
    "qb": {
        "numericSQLType": "CF_SQL_INTEGER"
    }
};

Bindings

Bindings are the values that will be sent as parameters to a prepared SQL statement. This protects you from SQL injection. In CFML, this uses cfqueryparam to parameterize the values.

If you need to inspect the bindings for the current query you can retrieve them in order using the getBindings method.

getBindings

This method returns the current bindings in order to be used for the query.

QueryBuilder
query.from( "users" )
    .join( "logins", function( j ) {
        j.on( "users.id", "logins.user_id" );
        j.where( "logins.created_date", ">", dateAdd( "m", -1, "01 Jun 2019" ) );
    } )
    .where( "active", 1 );

Result
[
    { value = "01 May 2019", cfsqltype = "CF_SQL_TIMESTAMP"  },
    { value = 1, cfsqltype = "CF_SQL_NUMERIC" }
]

You can also retrieve the bindings associated to their corresponding types.

getRawBindings

This method returns the current bindings to be used for the query associated to their corresponding types.

QueryBuilder
query.from( "users" )
    .join( "logins", function( j ) {
        j.on( "users.id", "logins.user_id" );
        j.where( "logins.created_date", ">", dateAdd( "m", -1, "01 Jun 2019" ) );
    } )
    .where( "active", 1 );

Result
{
    "commonTables" = [],
    "select" = [],
    "join" = [
        { value = "01 May 2019", cfsqltype = "CF_SQL_TIMESTAMP"  },
    ],
    "where" = [
        { value = 1, cfsqltype = "CF_SQL_NUMERIC" }
    ],
    "union" = [],
    "insert" = [],
    "insertRaw" = [],
    "update" = []
};
