FROM table- Must be escaped as an identifier SELECT id FROM?- Also identifier quoting SELECT id FROM table WHERE? LIKE?- With either the first or second parameter being a column referenceUsing Sprintf is no option, since the identifiers need to be properly quoted. The quoting and escaping is inherently vendor specific and may even depend on configuration on a per database/connection basis (hello there MySql.). What did you expect to see?The driver must export Quoting which are passed along by the database/sql Api.

SQL Injection is an exploit of an improperly formatted SQL query. The root of SQL injection is the mixing of code and data. In fact, an SQL query is a program. A fully legitimate program - just like our familiar PHP scripts. And so it happens that we are creating this program dynamically.

As far as I can tell the folling functions are needed. QuoteString: quotes and escapes a string so it can be used as a string literal (ex: mysqlrealescapestring). QuoteIdentifier: quote and escapes a string so it can be used as an identifier. QuoteBinary: quote and escapes binary data (ex: PQescapeBytea).

I am not sure if all identifiers are quoted consistently among all Databases. It might be that separate functions are needed depending on the type of the identifier.What did you see instead?No escaping/quoting functions. I would argue to the contrary.

Escaping primitives are needed for working securely with databases and they are inherently dependent on the SQL-server behind the connection. A package using database.sql might not even know what server it is talking to and how to properly quote and escape for that server, if it just gets passed a reference.As is, database.sql can only be used for queries known ahead of time and under the constraint, that the only dynamic entities in the query are value and never columns (think ORDER BY ) or tables. Good point about MySQL especially. I've updated the calls to be network friendly.You can get the driver from sql.DB.Driver so while it isn't a direct method from it in this shim, you can use in in a similar way right now.Here's what I'd like to see:. evolve and verify the API that is in sqlexp,. get a few drivers to implement it (they usually appreciate PRs),. then if it makes sense (which I think it would at that point), bring it into the std lib.Perhaps it would be good to combine the escaper functions with the database name function.

We'd probably want to make it easy to expand it in the future as well, which would mean changing it into a struct with methods. Even though MySQL behavior is different ANSIQUOTES, 'You can still use to quote identifiers with this mode enabled.' We can use backslash always. It meansQuoteIdentifier` doesn't need connection.It can be added to Driver directly, instead of connection.On the other hand, QueryString can not chose how to escape backslash withoutNOBACKSLASHESCAPE variable.But if we want to add it on Driver, I think it's OK to assume NOBACKSLASHESCAPEis disabled.BTW, if we add QuoteString, why no FormatDate, FormatDecimal, FormatFloat, FormatGeometry,FormatJSON, etc, etc.?I am very unsure about database/sql/driver should provide such helper functions to build SQL.How about API like DB.FormatSQL(sqlWithPlaceHolder string, args. Driver.Value) (string, error)?Note that QuoteIdentifier is special, because we can not use placeholder for it on some RDB including MySQL. So QuoteIdentifier will be worth enough even if DB.FormatSQL is added.You can copy escaping code from go-sql-driver/mysql.

I have a WordPress plugin that at one point I need to see if a certain title exists in the database. For 2 years, this code worked fine: $myposttitle= $wpdb-getresults('select posttitle from $wpdb-postswhere posttitle like '%'. '%');However, with php 5.5. And WP 3.9.1, this causes an error because the function mysqlrealescapestring is deprecated.Any ideas on what other function will properly escape the contents of $myTitle now that I can't use mysqlrealescapestring anymore?Thanks. While the prepare answer given is partially correct, if you do need a way to escape a string for an SQL statement manually, use escsql.For the specific case of escaping a string to be placed inside a like statement, then it should more correctly be written like this: $query = $wpdb-prepare('SELECT posttitle from $wpdb-postsWHERE posttitle LIKE%s','%'.

$wpdb-esclike( $myTitle ). '%');The $wpdb-esclike is necessary so as to properly escape any percent signs, underscores, or backslashes that may be in the phrase being searched for. Note that $wpdb-esclike does not return prepared input, it only escapes the special characters used in a LIKE.

Thus, the prepare is still needed. Farm frenzy 2 save game.
