i have two table
and table two data is
and i want to show just like this
I have to make a table out of two other tables one table with column word and serial and another with column meaning
and serial.
Now what I have to do is put this result(data)
into table3 (a table i already have, with the same columns as in table1 and (table2) tried lots but can't please help me
I hope this isn't too confusing of a question.
select
a.serial,
b.word,
a.word as meaning
from tbl1 a
join tbl2 b on a.serial = b.serial
This is the sql query your looking for ,details related to the same is been provided in the link below
INSERT INTO table3 (serial,word,meaning)
SELECT t1.serial,t2.word,t1.word
FROM table1 as t1
JOIN table2 as t2 ON t1.serial=t2.serial

Try

I Have Two Tables , Table1 Contains 10 Users Regular Data, Table2 Contains 3 vip users username(same as table1) only . Now how can I Get All 7 Non-VIP Users data using sql? Platform IS sqlite Database Android
Somnath,
It would be great if you would provide the database platform and actual table schemas in your question. Not having this information requires people to make assumptions. Anyway, I think it would like like this.
select *
from table1
where not exists(select * from table2 where table2.username = table1.username)
Something like:
SELECT * from Table1
WHERE user_id
NOT IN (SELECT user_id from Table2);
Translating to: Select everything in Table 1 where user_id doesn't exist in list of user_id's from Table2.
Table1 is Virtual Table with fts4 and TABLE2 is normal table.
Query1 (WORKS)
SELECT * FROM TABLE1 LEFT OUTER JOIN TABLE2 ON TABLE1.id=TABLE2.id WHERE TABLE1 MATCH 'sometext' LIMIT %d,%d
Query 2 (DOES NOT WORK)
SELECT * FROM TABLE2 LEFT OUTER JOIN TABLE1 ON TABLE1.id=TABLE2.id WHERE TABLE1 MATCH 'sometext' LIMIT %d,%d
Error from Query2
android.database.sqlite.SQLiteException: unable to use function MATCH
in the requested context (code 1)
From this it seems like FTS tabl need to be first on LEFT OUTER JOIN. Why this happening? Join happens first before applying WHERE clause. so if it was not working for table type mismatch i was assuming it would not work with query1 either. Anyone please explain this. what does happening internally? Also Any link to reference site would be appreciated explaining this.
MATCH works only on the FTS table itself, so it must be executed before the join.
In the second query, the database looks up matching rows first (with an outer join, it has no choice in the join order), and that temporary result is no longer an FTS table.
When using FTS, it usually is a better idea to move the FTS search (or the other search) into a subquery:
SELECT *
FROM Table2 LEFT JOIN (SELECT *
FROM Table1
WHERE Table1 MATCH ...)
USING (id);
I'm super-novice at Android programming and have this project I'm stuck on.
I have a database of (conlang) dictionaries where each language is in its own table. The user searches these and the results will display in a ListView. Right now, I've got it working to search only one table.
I want it to be able to search all three tables and display the results in one ListView with rows from each of the tables. I'd like to indicate which table each row came from. The results would display something like:
From language
Lang Term : English term
Additional information
I've set up a CursorAdapter and have this currently working for one of the three tables.
...
Since the dictionaries came from different sources, they have different information. As an example:
One has the columns EngTerm, VLangTerm, FullDefinition
Another has EngTerm, RLangTerm, PartOfSpeech
And the other has EngTerm, GLangTerm, PartOfSpeech, and PronounciationGuide (possibly).
For example, table1 might contain results for "land," "landing gear" and "landscape" and table2 might contain "land," "landing" and "island" and table3 might contain "bland" and "homeland."
The user can search these tables right now only by the english term, and can select to match by full word or partial word.
Because of how they are structured, I'm guessing there is no way to do a JOIN query.
I don't know if this helps at all, but right now, I've got this method in my SQLiteOpenHelper class:
public Cursor searchDictionaryByEnglish
(boolean matchFullWordOnly, String searchTerm) {
String sql = "SELECT * FROM " + TABLE_VULCAN +
" WHERE " + COLUMN_ALL_ENG_TERM + " MATCH ?";
if (!matchFullWordOnly)
searchTerm = "*" + searchTerm + "*";
return mDataBase.rawQuery(sql, new String[]{searchTerm});
}
(It is an FTS3 table it's searching, thus the MATCH rather than LIKE.)
I hope I've made it clear what I'm trying to accomplish, but I'm not sure where to start. I've found some answers about MergeCursor but I don't know how to apply that because of the different number and names of columns.
Here's how to do a union if you don't have one of the columns in one of the tables, it will work if you're only searching through the common column, that all the tables have.
SELECT field1 ,
field2 ,
field3
FROM ( SELECT field1 ,
field2 ,
field3
FROM table1
UNION
SELECT field1 ,
field2 ,
field3
FROM table2
UNION
SELECT field1 ,
field2 ,
NULL AS field3
FROM table3
) tbl
WHERE tbl.field1 LIKE '%search_string%'
Note the NULL AS field3 in the last UNION.
Create a Adapter that does accept the fields you require to display.
I need to join two tables into a relational table. I know that I can do this with inner join but I don't know how to start.
TABLE_SOCIO
-----------------
-id
-name
-phone
-email
TABLE QUOTA
-----------------
-id
-name
-description
-value
Now I need to join this two in on unique table by the id's of each.
RELATIONAL TABLE
-----------------
-id_Quota
-id_Socio
I have one id_Quota to n id's_Socio. It's a relation 1-n. I have an array list with the set of id_Socio that I need to save in relational table with only one id_Quota.
Any ideas? How I can start with inner join? Foreign key it's need?
Any example?
SELECT t1.name, t1. phone,
t2.description, t2.value
FROM TABLE_SOCIO t1
INNER JOIN RELATIONALTABLE r ON t1.Id = r.id_Socio
INNER JOIN TABLE_QUOTA t1 ON t2.Id = r.id_Quota
Suppose I have two database files a.sqlite and other one is b.sqlite. suppose table1 is in a.sqlite and table2 in b.sqlite. I open a.sqlite in read-only mode and b.sqlite in read-write.Suppose both table table1 and table2 has same column name "description".table2 has description column with all null values and table1 has some values.So how can i add the data from table1 into table2.I know through query.But as these r in two different databse,so is there ant problem? Can any one suggest ?
Not sure if your environment allows it, but ATTACH DATABASE is normally the way to go:
