The SqlCeParameter type exposes the following members.
Constructors
Name | Description | |
---|---|---|
SqlCeParameter() | Initializes a new instance of the SqlCeParameter class. | |
SqlCeParameter(String, SqlDbType) | Initializes a new instance of the SqlCeParameter class with the parameter name and data type. | |
SqlCeParameter(String, Object) | Initializes a new instance of the SqlCeParameter class with the parameter name and the value of the new SqlCeParameter. | |
SqlCeParameter(String, SqlDbType, Int32) | Initializes a new instance of the SqlCeParameter class with the parameter name, data type, and length. | |
SqlCeParameter(String, SqlDbType, Int32, String) | Initializes a new instance of the SqlCeParameter class with the parameter name, data type, length, and source column name. | |
SqlCeParameter(String, SqlDbType, Int32, Boolean, Byte, Byte, String, DataRowVersion, Object) | Initializes a new instance of the SqlCeParameter class with the parameter name, data type, length, and other properties. SQL Server Compact supports only input parameters. | |
SqlCeParameter(String, SqlDbType, Int32, ParameterDirection, Boolean, Byte, Byte, String, DataRowVersion, Object) | Initializes a new instance of the SqlCeParameter class with the parameter name, data type, length, parameter direction, and other properties. SQL Server Compact only supports input parameters. |

Properties
Name | Description | |
---|---|---|
DbType | Gets or sets the DbType of the parameter. (Overrides DbParameter.DbType.) | |
Direction | This property always returns ParameterDirection.Input for .NET Compact Framework Data Provider for SQL Server Compact. Setting this property to a different value causes an InvalidOperationException to be thrown. (Overrides DbParameter.Direction.) | |
IsNullable | Gets or sets a value indicating whether or not the parameter accepts null values. (Overrides DbParameter.IsNullable.) | |
Offset | Infrastructure. | |
ParameterName | Gets or sets the name of the SqlCeParameter. (Overrides DbParameter.ParameterName.) | |
Precision | Gets or sets the maximum number of digits used to represent the Value property. | |
Scale | Gets or sets the number of decimal places to which Value is resolved. | |
Size | Gets or sets the maximum length of the data within the column. (Overrides DbParameter.Size.) | |
SourceColumn | Gets or sets the name of the source column mapped to the DataSet and used for loading or returning the Value. (Overrides DbParameter.SourceColumn.) | |
SourceColumnNullMapping | Infrastructure. (Overrides DbParameter.SourceColumnNullMapping.) | |
SourceVersion | Gets or sets the DataRowVersion to use when loading Value. (Overrides DbParameter.SourceVersion.) | |
SqlDbType | Gets or sets the SqlDbType of the parameter. | |
Value | Gets or sets the value of the parameter. (Overrides DbParameter.Value.) |

Examples
The following example shows a typical use of SqlCeParameter.
Dim param As New SqlCeParameter("@Description", SqlDbType.NVarChar)
param.Value = "garden hose"
SqlCeParameter param = new SqlCeParameter("@Description", SqlDbType.NVarChar);
param.Value = "garden hose";
