<title>ToDo List</title>

<para>

This version of the preprocessor has some flaws:

<variablelist>

<varlistentry>

<term>Library functions</term>

<listitem>

<para>

to_date et al. does not exist. However,

<productname>PostgreSQL</productname> has some good conversion

routines so you probably won't miss them.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>Structures and unions</term>

<listitem>

<para>

Structures and unions have to be defined in the

<command>declare</> section.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>Missing statements</term>

<listitem>

<para>

The following statements are not implemented thus far:

<itemizedlist>

<listitem>

<para>

<literal>exec sql allocate</>

</para>

</listitem>

<listitem>

<para>

<literal>exec sql deallocate</>

</para>

</listitem>

<listitem>

<para>

<literal>SQLSTATE</>

</para>

</listitem>

</itemizedlist>

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>message 'no data found'</term>

<listitem>

<para>

The error message for <quote>no data</quote> in:

<programlisting>

exec sql insert select from statement

</programlisting>

has to be <literal>100</>.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term><literal>sqlwarn[6]</literal></term>

<listitem>

<para>

<literal>sqlwarn[6]</literal> should be <literal>W</> if the <command>PRECISION</>

or <command>SCALE</> value specified in a <command>SET

DESCRIPTOR</> statement was ignored.

</para>

</listitem>

</varlistentry>

</variablelist>
