I'm trying to search a database for a string. Im very new to SQLite so please excuse my ignorance I setup the call as follows
public void GetContact() {
//---get a contact---
EditText mEdit = (EditText)findViewById(R.id.editTextnum);
mEdit.setText("A000021");
db.open();
Cursor c = db.getAsset(mEdit.getText());
if (c.moveToFirst())
DisplayContact(c);
else
Toast.makeText(this, "No contact found", Toast.LENGTH_LONG).show();
db.close();
}
This fills a edittext with the string "A000021" and then runs the procedure in the DB helper "getAsset" using the contents of the edittext as the search string
The get Asset procedure is as follows
public Cursor getAsset(Editable strname) throws SQLException
{
Cursor mCursor =
db.query(true, DATABASE_TABLE, new String[] {KEY_ROWID,KEY_NAME, KEY_EMAIL,KEY_FLOOR,KEY_ROOMID,KEY_SCHOOLID,KEY_CONDITION,KEY_ASSETNUMBER,KEY_ASSETCATEGORY,KEY_ASSETTYPE,KEY_ADDITIONAL,KEY_MANUFACTURER,KEY_TYPE,KEY_SERIAL,KEY_INFO,KEY_QUANTITY,KEY_COMMENTS,KEY_INSTALL,KEY_VERIFIED}, KEY_ASSETNUMBER + "=" + strname, null,null, null, null, null);
if (mCursor != null) {
mCursor.moveToFirst();
}
return mCursor;
}
when I run its says
android.database.sqlite.SQLiteException: no such column: A000021 (code 1): , while compiling: SELECT DISTINCT _id, SITE, BUILDING, FLOOR, ROOMID, SCHOOLID, CONDITION, ASSETNUMBER, ASSETCATEGORY, ASSETTYPE, ADDITIONAL, MANUFACTURER, TYPEMODEL, SERIALNUMBER, INFORMATION, QUANTITY, COMMENTS, INSTALLDATE, VERIFIED FROM contacts WHERE ASSETNUMBER=A000021
The column is called ASSETNUMBER it is a text column and im looking to return the record that has an assetnumber of A000021
Any ideas where I'm going wrong?
尝试使用类似功能
db.query(true, DATABASE_TABLE, new String[] {KEY_ROWID,KEY_NAME, KEY_EMAIL,KEY_FLOOR,KEY_ROOMID,KEY_SCHOOLID,KEY_CONDITION,KEY_ASSETNUMBER,KEY_ASSETCATEGORY,KEY_ASSETTYPE,KEY_ADDITIONAL,KEY_MANUFACTURER,KEY_TYPE,KEY_SERIAL,KEY_INFO,KEY_QUANTITY,KEY_COMMENTS,KEY_INSTALL,KEY_VERIFIED}, KEY_ASSETNUMBER + " like '" + strname+"' ", null,null, null, null, null);
