> Key: IBATISNET-49
> URL: http://issues.apache.org/jira/browse/IBATISNET-49
> Project: iBatis for .NET
> Type: Bug
> Versions: DataMapper 1.1
> Environment: [assembly: AssemblyVersion("1.1.458")]
> Reporter: Ron Grabowski
> Assignee: Roberto Rabe
> Fix For: DataMapper 1.2
>
> SQLite:
> http://www.sqlite.org/
> doesn't have strongly typed data columns like most other databases. The
> SQLite.Net provider:
> http://sourceforge.net/projects/adodotnetsqlite
> throws NotSupportedExceptions when code like this is executed:
> ((IDbDataParameter)dataParameter).Precision = property.Precision;
> [NotSupportedException: Specified method is not supported.]
> Finisar.SQLite.SQLiteParameter.set_Precision(Byte value)
>
> IBatisNet.DataMapper.Configuration.Statements.PreparedStatementFactory.CreateParametersForStatementText()
> A naive way to solve this is to simply wrap the setting of IDbDataParameter
> properties in a try/catch block:
> try
> {
> // Set IDbDataParameter
> if (property.Size != -1)
> {
> ((IDbDataParameter)dataParameter).Size = property.Size;
> }
> ((IDbDataParameter)dataParameter).Precision = property.Precision;
> ((IDbDataParameter)dataParameter).Scale = property.Scale;
> }
> catch
> {
> }
> This thread:

> http://www.mail-archive.com/ibatis-user-cs@incubator.apache.org/msg00317.html
> talks about similiar issues with an Oracle provider that can be solved by not
> setting the certain IDbDataParameter properties. Perhaps it may be worthwhile
> to look into adding additional attributes to the <provider> nodes in
> providers.config to specify which properties of the IDbDataParameter to set.
> For example this is how a <provider> entry may look after incorporating this
> idea as well as ideas from IBATISNET-48 and IBATISNET-47:
> <provider
> name="SQLite3"
> enabled="true"
> assemblyName="SQLite.NET, Version=0.21.1869.3794, Culture=neutral,
> PublicKeyToken=c273bd375e695f9c"
> connectionClass="Finisar.SQLite.SQLiteConnection"
> commandClass="Finisar.SQLite.SQLiteCommand"
> parameterClass="Finisar.SQLite.SQLiteParameter"
> parameterDbTypeClass="System.Data.DbType, System.Data"
> parameterDbTypeProperty="DbType"
> dataAdapterClass="Finisar.SQLite.SQLiteDataAdapter"
> commandBuilderClass="Finisar.SQLite.SQLiteCommandBuilder"
> usePositionalParameters = "true"
> useParameterPrefixInSql = "false"
> useParameterPrefixInParameter = "false"
> parameterPrefix=""
> setDbParameterPrecision="false"
> setDbParameterScale="false"
> setDbParameterSize="false"
> />
