My SQLLite query is not working properly. See below:
UUID i=UUID.randomUUID();
String Beregero ="INSERT INTO
contacts(id,uuid,name,phone,email,street,city,state,zip) " +
" VALUES(3,"+"'"+i.toString()+"'"+",'Patrice
Beregeron','978-555-1212','pBeregero#BostonBruins.com'," +
"'1 causeway street','Boston','Mass','01236');";
db.execSQL(Beregero);
I am receiving the following error in my log:
(table contacts has no column named uuid (code 1): , while
compiling: INSERT INTO contacts(id,uuid,name,phone,email,
street,city,state,zip) VALUES(3,'12ee5bbf-dabb-4d95-bfe7-6e6f14702add',
'Patrice Beregeron','978-555-1212','pBeregero#BostonBruins.com',
'1 causeway street','Boston','Mass','01236');)

The exception says it all, your table has no column name uuid created. So uninstall the app, then run it again. This error occurs only if the column is not generated.
The error message in you log clearly states the problem. The contacts table does not have a column uuid. You now could do the following:
Check if you have got right lower case vs. upper case. The column in question might be UUID instead of uuid (I don't know SQLite, but case matters in many database systems).
If the column really is not in the table yet, then add it (either by code or by hand). Read SQLite's documentation to learn how to that (I can't help you here because I don't know SQLite).
Uninstalling and re-installing the app would help only if the app would generate the database upon installing or during the first run. Since we don't know anything about the app, this might or might not be the case.
You have not added the column "uuid" in the create table "contacts" query like this :
String createTableContacts = "create table contacts ( ' uuid text ')";

I'm trying out statements for creating a database, and after 10 entities without any issues I ran into this error
Error: Near line 83: near "Transaction": syntax error
The first line is line 83 with it's context of creating a table
CREATE TABLE Transaction (
TransactionID INTEGER,
AccountID INTEGER REFERENCES User (AccountID),
ItemID INTEGER REFERENCES Item (ItemID),
Method STRING,
Price INTEGER,
TransactionDate DATE,
PRIMARY KEY (TransactionID)
);
Now I can't seem to find the issue, and suggestion's of something with ASCII using the wrong space couldn't be solved by writing the same thing again manually.
I haven't even gotten around to checking the integrity of my foreign keys, and it's not working. Hopefully somebody could provide some insight on what I'm missing.
Transaction is one of the reserved names in SQLite. For a full list see here.
Ways to solve this issue are:
Change the Table name to a word that isn't reserved.
or
Quote the reserved name by using one of these 4 listed quote marks
'keyword'
"keyword"
[keyword]
`keyword`
Is there a way to access the SQLiteLog or at least pipe out errors to do with SQLite?
I would like to automatically send any errors, like the below, so I can optimise the database by adding in indexes, or making other changes as need be.
E/SQLiteLog: (284) automatic index on messages(chat_id)
It could well be that I'd only want to catch code 284, rather than getting everything. Is there a way of doing this when building the app, as would be useful to pass to crashlytics to help with development going forward
A potential alternative, would be to run the queries preceded with EXPLAIN QUERY PLAN, and to then check for AUTOMATIC COVERING INDEX in the results.
e.g.
DROP TABLE IF EXISTS table1;
DROP TABLE IF EXISTS table2;
CREATE TABLE IF NOT EXISTS table1 (column1 TEXT, column2 TEXT);
CREATE TABLE IF NOT EXISTS table2 (column3, column4);
EXPLAIN QUERY PLAN
SELECT * FROM table1, table2 WHERE column1=column3;
Results in :-
As you can see this is based upon a predication of the number of rows rather than the actual number of rows, so works if there is no data (as above), which could well be beneficial, from a development perspective, as opposed to trying to trap on a as happens basis.
Developing an Android app, but this is a SQLite question.... My SQL is much ropier than my Java.
This is the SQL (copied from a log file, in code it's constructed from various constants):
CREATE VIEW albums (_id, name , type ) AS SELECT rowno, name, subtype FROM metadata WHERE subtype = 'album'
but it throws:
android.database.sqlite.SQLiteException: near "(": syntax error (code 1): , while compiling:
Specifying column names in the view seems to me to be clearly permitted, if I understand the flow chart in the sqlite documentation here, and at this time of night I really can't see what's wrong. I have tried changing the name of the _id column in case it was something to do with the initial underscore, but to no avail and in any case I will need the _id column later for the CursorAdapter that will end up using this View.
At the bottom of the documentation page you linked it states:
Note that the column-name list syntax is only supported in SQLite
versions 3.9.0 and later.
Version 3.9.0 is not supported by Android. Lollipop has 3.7.11. Marshmallow has 3.8.10.2.
I have created one Member_Master table whose primary key is member_id in sqlite manager for android and creating foreign key in child table e.g Event_Master for member_id from Member_Master. I was getting no such table found:Member_Master error
But now I am getting the following error :
SQLiteManager: CREATE TABLE "main"."Events_Master" ("event_id" NUMERIC PRIMARY KEY NOT
NULL ,"event_name" TEXT NOT NULL ,"event_details" TEXT NOT NULL ,"event_start_date"
DATETIME NOT NULL ,"event_end_date" DATETIME NOT NULL ,"event_time" DATETIME NOT NULL
,"event_venue" TEXT NOT NULL ,"min_level" NUMERIC,"status_id" NUMERIC,"member_id"
NUMERIC, foriegn key(member_id) references Member_Master(member_id)ON DELETE CASCADE ON
UPDATE CASCADE) [ near "member_id": syntax error ]
Exception Name: NS_ERROR_FAILURE
Exception Message: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE)
[mozIStorageConnection.createStatement]
Please give me the solution. Since Member_Master table is already created and field name is member_id only.
If you are getting no such table exception, the reason for this is that the table is not created.There can be few reasons like
1 ) The command you have used to create the table is is wrong (and could be a typing error also).
2 ) You are adding a table in an already existing database
When Database is created with specific number of tables you can not add more tables to it .
If you want to add more tables, you need to uninstall the application from your emulator and install the application again only then it shall create the new tables by re creating the database.
Or upgrade the database version , it shall drop all the tables once and then recreate the database.
Try uninstalling the app and reinstall it again. it works most of the times.
If you are getting no such table exception, then It is sure that the tables are not getting created.Have You written create Table query in your DatabaseAdapter class or simply adding a table from SqliteManager.
If you are creating tables dynamically, please write CREATE TABLE query and execute Query.
This line, mDatabase.execSQL(sql);, gives me the following error:
{ sqlite returned: error code = 1, msg = near "*": syntax error }
for Delete * from table_name Query
My SQL query is : DELETE * FROM table_name
How can I solve this?
DELETE * FROM table_name is a wrong sql command. Use DELETE from table_name
Syntax error means that basically your statement is spelled wrong and it can not be parsed. In this case error message states where exactly this error occurred - on "*" character. In such case you should go to database documentation and check proper syntax of the command you are trying to use. In case of SQLite it's here. You can find documentation about DELETE statement there, here is the link. It shows you the syntax in graphical way (called syntax diagrams or railroad diagrams) which should be quite easy to follow.
In this case, as mentioned earlier, you just can't specify "*" between DELETE and FROM. This is because you are always deleting whole rows and you can't delete individual selected columns.
If you need to delete the entire table can you use DROP TABLE IF EXISTS then recreate the table
