    if (!table.tableIsExist())
        return 0;
    DbModelSelector dmSelector = this.select("count(\"" + table.getId().getName() + "\") as count");
    DbModel firstModel = dmSelector.findFirst();
    if (firstModel != null) {
        return firstModel.getLong("count");
    }
    return 0;
}

Example 2 with DbModel

use of org.xutils.db.table.DbModel in project xUtils3 by wyouflf.

the class CursorUtils method getDbModel.

public static DbModel getDbModel(final Cursor cursor) {
    DbModel result = new DbModel();
    int columnCount = cursor.getColumnCount();
    for (int i = 0; i < columnCount; i++) {
        result.add(cursor.getColumnName(i), cursor.getString(i));
    }

Example 3 with DbModel

use of org.xutils.db.table.DbModel in project xUtils3 by wyouflf.

the class DbFragment method onTestDbClick.

    // 一对多: (本示例的代码)
    // 自己在多的一方(child)保存另一方的(parentId), 查找的时候用parentId查parent或child.
    // 一对一:
    // 在任何一边保存另一边的Id并加上唯一属性: @Column(name = "parentId", property = "UNIQUE")
    // 多对多:
    // 再建一个关联表, 保存两边的id. 查询分两步: 先查关联表得到id, 再查对应表的属性.
