摘要：最近在公司接觸到了的框架，研究了一下官方文檔，做了以下整理其他定義方法字段類型是否允許為字段是否自定義表名是否需要增加字段不需要字段將字段改個名將字段改名同時需要設(shè)置為此種模式下，刪除數(shù)據(jù)時不會進(jìn)行物理刪除，而是設(shè)置為當(dāng)前時間

最近在公司接觸到了sequelize(Nodejs的ORM框架)，研究了一下官方文檔，做了以下整理

let DeviceInterface = Sequelize.define("DeviceInterface", {
        name: {
            type: Sequelize.STRING,
            allowNull: false
        },
        createBy: {
            type: Sequelize.INTEGER,
            defaultValue: "-1"
        },
        image: {
            type: Sequelize.STRING
        },
        desc: {
            type: Sequelize.STRING
        }
    }, {
        tableName: "DeviceInterface"
    });

Sequelize.STRING                      // VARCHAR(255)
Sequelize.STRING(1234)                // VARCHAR(1234)
Sequelize.STRING.BINARY               // VARCHAR BINARY
Sequelize.TEXT                        // TEXT
Sequelize.TEXT("tiny")                // TINYTEXT

Sequelize.INTEGER                     // INTEGER

Sequelize.BIGINT(11)                  // BIGINT(11)

Sequelize.FLOAT                       // FLOAT
Sequelize.FLOAT(11)                   // FLOAT(11)

Sequelize.DOUBLE                      // DOUBLE
Sequelize.DOUBLE(11)                  // DOUBLE(11)
Sequelize.DOUBLE(11, 12)              // DOUBLE(11,12)

Sequelize.DECIMAL                     // DECIMAL
Sequelize.DECIMAL(10, 2)              // DECIMAL(10,2)

Sequelize.DATE                        // DATETIME for mysql / sqlite, TIMESTAMP WITH TIME ZONE for postgres
Sequelize.DATE(6)                     // DATETIME(6) for mysql 5.6.4+. Fractional seconds support with up to 6 digits of precision 
Sequelize.DATEONLY                    // DATE without time.
Sequelize.BOOLEAN                     // TINYINT(1)

Sequelize.ENUM("value 1", "value 2")  // An ENUM with allowed values "value 1" and "value 2"
Sequelize.ARRAY(Sequelize.TEXT)       // Defines an array. PostgreSQL only.

Sequelize.JSON                        // JSON column. PostgreSQL only.
Sequelize.JSONB                       // JSONB column. PostgreSQL only.

Sequelize.BLOB                        // BLOB (bytea for PostgreSQL)
Sequelize.BLOB("tiny")                // TINYBLOB (bytea for PostgreSQL. Other options are medium and long)

Sequelize.UUID                        // UUID datatype for PostgreSQL and SQLite, CHAR(36) BINARY for MySQL (use defaultValue: Sequelize.UUIDV1 or Sequelize.UUIDV4 to make sequelize generate the ids automatically)

Sequelize.RANGE(Sequelize.INTEGER)    // Defines int4range range. PostgreSQL only.
Sequelize.RANGE(Sequelize.BIGINT)     // Defined int8range range. PostgreSQL only.
Sequelize.RANGE(Sequelize.DATE)       // Defines tstzrange range. PostgreSQL only.
Sequelize.RANGE(Sequelize.DATEONLY)   // Defines daterange range. PostgreSQL only.
Sequelize.RANGE(Sequelize.DECIMAL)    // Defines numrange range. PostgreSQL only.

Sequelize.ARRAY(Sequelize.RANGE(Sequelize.DATE)) // Defines array of tstzrange ranges. PostgreSQL only.

Sequelize.GEOMETRY                    // Spatial column.  PostgreSQL (with PostGIS) or MySQL only.
Sequelize.GEOMETRY("POINT")           // Spatial column with geometry type.  PostgreSQL (with PostGIS) or MySQL only.
Sequelize.GEOMETRY("POINT", 4326)     // Spatial column with geometry type and SRID.  PostgreSQL (with PostGIS) or MySQL only.

var User = sequelize.define(

        // 同時需要設(shè)置paranoid為true（此種模式下，刪除數(shù)據(jù)時不會進(jìn)行物理刪除，而是設(shè)置deletedAt為當(dāng)前時間
        "deletedAt": "dtime",
        "paranoid": true
