Many of the utility methods in ScriptUtils are public only because they
were once invoked from JdbdTestUtils in spring-test, which is no longer
the case. Consequently, there should no longer be a need for any
external clients to invoke such methods.
To address, this commit formally deprecates the following methods in
ScriptUtils in spring-jdbc.
- readScript(...)
- containsSqlScriptDelimiters(...)
- splitSqlScript(...)
Closes gh-26947
Prior to this commit, the implementation of
ScriptUtils.containsSqlScriptDelimiters() did not ignore comments when
searching for the statement delimiter within an SQL script. This
resulted in subtle bugs if a comment contained a single single-quote or
single double-quote, since the absence of the closing single-quote or
double-quote led the algorithm to believe that it was still "within a
text literal". Similar issues could arise if a comment contained the
sought statement delimiter but the rest of the script did not contain
the sought statement delimiter. In such cases, the algorithms in
ScriptUtils could erroneously choose an incorrect statement delimiter
-- for example, using the fallback statement delimiter instead of the
delimiter specified by the user.
This commit avoids such bugs by ignoring single-line comments and block
comments when searching for the statement delimiter within an SQL
script.
Closes gh-26911
Prior to this commit, the containsSqlScriptDelimiters() method in
ScriptUtils ignored delimiters enclosed in single quotes but not those
enclosed within double quotes, which contradicts the algorithm in
splitSqlScript() and therefore constitutes a bug.
This commit fixes this bug in the ScriptUtils implementation in
spring-jdbc.

Prior to this commit, if an SQLException was thrown while retrieving
column metadata from the database, SimpleJdbcInsert would generate an
INSERT statement that was syntactically valid but missing columns,
which could lead to data silently missing in the database (for nullable
columns).
This commit fixes this by clearing all collected column metadata if an
SQLException is thrown while processing the metadata. The result is
that an InvalidDataAccessApiUsageException will be thrown later while
generating the INSERT statement. The exception message now contains an
additional hint to make use of SimpleJdbcInsert#usingColumns() in order
to ensure that all required columns are included in the generated
INSERT statement.
SimpleJdbcCall can also encounter an SQLException while retrieving
column metadata for a stored procedure/function, but an exception is
not thrown since a later invocation of the stored procedure/function
will likely fail anyway due to missing arguments. Consequently, this
commit only improves the warning level log message by including a hint
to make use of SimpleJdbcCall#addDeclaredParameter().
Closes gh-26486
Includes deprecation of JdbcUtils.extractDatabaseMetaData(DataSource, String) in favor of the now generified version of extractDatabaseMetaData(DataSource, DatabaseMetaDataCallback).

Hi guys,
We're facing an issue in our application when we try to call a procedure in Informix database,
our app uses standard JDBC (spring-jdbc and com.ibm.informix.jdbc.4.50.3) without Hibernate
to connect to the database
Issue:
When we trying to execute any procedure call in our Informix database there is no data returned.
Diagnostic:
It points to the Java class called CallMetaDataProviderFactory in spring-jdbc project.
Taking a look of this class there is no explicit support for Informix procedure calls, so I added "Informix Dynamic Server" to the
list of supported databases and now I can execute procedures call without issues.
Basically I added the line "Informix Dynamic Server" to the list called "supportedDatabaseProductsForProcedures"
of CallMetaDataProviderFactory class in my local environment and it worked as expected.
I really appreciate any feedback/suggestion for this approach due we would like to continue using the framework
normally in our development without losing updates using a workaround in our end.
Many thanks in advance.
