![]() ![]() Note − addslashes() should NOT be used to quote your strings for SQLite queries it will lead to strange results when retrieving your data. If (preg_match("/^\w'") Īlthough the encoding makes it safe to insert the data, it will render simple text comparisons and LIKE clauses in your queries unusable for the columns that contain the binary data. Tables may be created in the main database, the temp database, or in any attached database. The database in which the new table is created. In the following example, the username is restricted to alphanumerical chars plus underscore and to a length between 8 and 20 chars - modify these rules as needed. A CREATE TABLE command specifies the following attributes of the new table: The name of the new table. Never trust user provided data, process this data only after validation as a rule, this is done by pattern matching. Injection usually occurs when you ask a user for input, like their name, and instead of a name they give you a SQLite statement that you will unknowingly run on your database. In this chapter, you will learn how to help prevent this from happening and help you secure your scripts and SQLite statements. First, let's learn SELECT and WHERE clauses which will be covered in subsequent chapters.If you take user input through a webpage and insert it into a SQLite database there's a chance that you have left yourself wide open for a security issue known as SQL Injection. INSERT INTO first_table_name įor now, you can skip the above statement. You can populate data into a table through select statement over another table provided another table has a set of fields, which are required to populate the first table. In the next chapter, you will learn how to display all these records from a table. INSERT INTO COMPANY VALUES (7, 'James', 24, 'Houston', 10000.00 ) Īll the above statements would create the following records in COMPANY table. You can create a record in COMPANY table using the second syntax as follows − Once you have the SQLite.NET library available, follow these three steps to use it to access a database: Add a using statement Add the following statement to the C files where data access is required: C. VALUES (1, 'Paul', 32, 'California', 20000.00 ) SQLite.NET is a third-party library that's supported from the praeclarum/sqlite-net repo. INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) Now, the following statements would create six records in COMPANY table. INSERT INTO TABLE_NAME VALUES (value1,value2,value3.valueN) Ĭonsider you already have created COMPANY table in your testDB.db as follows − The SQLite INSERT INTO syntax would be as follows − ![]() However, make sure the order of the values is in the same order as the columns in the table. You may not need to specify the column(s) name in the SQLite query if you are adding values for all the columns of the table. Here, column1, lumnN are the names of the columns in the table into which you want to insert data. Syntaxįollowing are the two basic syntaxes of INSERT INTO statement. ![]() SQLite INSERT INTO Statement is used to add new rows of data into a table in the database. ![]()
