Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, PHP, and XML. Here, the first argument sqlite. SQLite. 3exec routine parses and executes every command given in the sql argument until it reaches the end of the string or encounters an error. This routine closes a database connection previously opened by a call to sqlite. All prepared statements associated with the connection should be finalized prior to closing the connection. If any queries remain that have not been finalized, sqlite. SQLITEBUSY with the error message Unable to close due to unfinalized statements. Connect To Database. Following C code segment shows how to connect to an existing database. If the database does not exist, then it will be created and finally a database object will be returned. Err. Msg 0. rc sqlite. Cant open database sn, sqlite. Opened database successfullyn. Now, lets compile and run the above program to create our database test. You can change your path as per your requirement. Opened database successfully. If you are going to use C source code, then you can compile your code as follows. Here, we are linking our program with sqlite. C program. This will create a database file test. May 8 0. 2 0. 6 a. May 8 0. 2 0. 5 test. May 8 0. 2 0. 6 test. Create a Table. Following C code segment will be used to create a table in the previously created database. Not. Used, int argc, char rgv, char az. Col. Name. fori 0 ilt argc i. Col. Namei, argvi NULL. Err. Msg 0. Open database. Cant open database sn, sqlite. Opened database successfullyn. Create SQL statement. CREATE TABLE COMPANY. ID INT PRIMARY KEY NOT NULL,. NAME TEXT NOT NULL,. AGE INT NOT NULL,. ADDRESS CHAR5. SALARY REAL. Execute SQL statement. Err. Msg. if rc SQLITEOK. SQL error sn, z. Err. Msg. sqlite. Err. Msg. fprintfstdout, Table created successfullyn. When the above program is compiled and executed, it will create COMPANY table in your test. May 8 0. 2 3. 1 a. May 8 0. 2 3. 1 test. May 8 0. 2 3. 1 test. INSERT Operation. Following C code segment shows how you can create records in COMPANY table created in the above example. Not. Used, int argc, char argv, char az. Col. Name. fori 0 ilt argc i. Col. Namei, argvi NULL. Err. Msg 0. Open database. Cant open database sn, sqlite. Opened database successfullyn. Create SQL statement. INSERT INTO COMPANY ID,NAME,AGE,ADDRESS,SALARY. VALUES 1, Paul, 3. California, 2. 00. INSERT INTO COMPANY ID,NAME,AGE,ADDRESS,SALARY. VALUES 2, Allen, 2. Texas, 1. 50. 00. INSERT INTO COMPANY ID,NAME,AGE,ADDRESS,SALARY. VALUES 3, Teddy, 2. Norway, 2. 00. 00. INSERT INTO COMPANY ID,NAME,AGE,ADDRESS,SALARY. VALUES 4, Mark, 2. Rich Mond, 6. 50. Execute SQL statement. Err. Msg. if rc SQLITEOK. SQL error sn, z. Err. Msg. sqlite. Err. Msg. fprintfstdout, Records created successfullyn. When the above program is compiled and executed, it will create the given records in COMPANY table and will display the following two lines. Opened database successfully. Records created successfully. SELECT Operation. Before proceeding with actual example to fetch records, let us look at some detail about the callback function, which we are using in our examples. This callback provides a way to obtain results from SELECT statements. It has the following declaration. Data provided in the 4th argument of sqlite. The number of columns in row. An array of strings representing fields in the row. An array of strings representing column names. If the above callback is provided in sqliteexec routine as the third argument, SQLite will call this callback function for each record processed in each SELECT statement executed within the SQL argument. Following C code segment shows how you can fetch and display records from the COMPANY table created in the above example. Col. Name. fprintfstderr, s, const chardata. Col. Namei, argvi NULL. Err. Msg 0. const chardata Callback function called. Open database. Cant open database sn, sqlite. Opened database successfullyn. Create SQL statement. Install Vim Color Scheme Linux Server. SELECT from COMPANY. Execute SQL statement. Err. Msg. if rc SQLITEOK. SQL error sn, z. Err. Msg. sqlite. Err. Msg. fprintfstdout, Operation done successfullyn. When the above program is compiled and executed, it will produce the following result. Opened database successfully. Callback function called ID 1. ADDRESS California. SALARY 2. 00. 00. Callback function called ID 2. ADDRESS Texas. SALARY 1. Callback function called ID 3. ADDRESS Norway. SALARY 2. Callback function called ID 4. ADDRESS Rich Mond. SALARY 6. 50. 00. Operation done successfully. UPDATE Operation. Following C code segment shows how we can use UPDATE statement to update any record and then fetch and display updated records from the COMPANY table. Col. Name. fprintfstderr, s, const chardata. Col. Namei, argvi NULL. Err. Msg 0. const chardata Callback function called. Open database. Cant open database sn, sqlite. Opened database successfullyn. Create merged SQL statement. UPDATE COMPANY set SALARY 2. ID1. SELECT from COMPANY. Execute SQL statement. Err. Msg. if rc SQLITEOK. SQL error sn, z. Err. Msg. sqlite. Err. Msg. fprintfstdout, Operation done successfullyn. When the above program is compiled and executed, it will produce the following result. Opened database successfully. Callback function called ID 1. ADDRESS California. SALARY 2. 50. 00. Callback function called ID 2. ADDRESS Texas. SALARY 1. Callback function called ID 3. Operation done successfully. DELETE Operation. Following C code segment shows how you can use DELETE statement to delete any record and then fetch and display the remaining records from the COMPANY table. Col. Name. fprintfstderr, s, const chardata. Col. Namei, argvi NULL. Err. Msg 0. const chardata Callback function called. Open database. Cant open database sn, sqlite. Opened database successfullyn. Create merged SQL statement. DELETE from COMPANY where ID2. SELECT from COMPANY. Execute SQL statement. Err. Msg. if rc SQLITEOK. SQL error sn, z. Err. Msg. sqlite. Err. Msg. fprintfstdout, Operation done successfullyn. When the above program is compiled and executed, it will produce the following result. Opened database successfully. Callback function called ID 1. ADDRESS California. SALARY 2. 00. 00. Callback function called ID 3. ADDRESS Norway. SALARY 2. Callback function called ID 4. ADDRESS Rich Mond. SALARY 6. 50. 00. Operation done successfully. Insert and Update image field in SQL Server 2. Few months back I have written one article which was showing how to store image and other files into SQL Server column by converting it to byte object and receive it back. That was with the help of C but now this time I am going to show, how you can insert and update image or varbinary field from within SQL Server itself. Before we move further, If you wish to look at my previous article with C script, please have a look at Ok, now let us move ahead with our script in SQL Server itself. SQL Server. INSERTINTO empsName,dept,emp. ImgselectROMOPENROWSETBULKC Ritesh. JPG,SINGLEBLOBAS img check the inserted data update your table, along with image also. ImgselectROMOPENROWSETBULKC Ritesh. JPG,SINGLEBLOBAS img, deptIT check the data whether it has been updated.
