Empty tables

In this particular case, you may find ADO Schemas useful.This will list fields and some properties for a particular table. Be careful of data types, you may not get an exact match to DAO types. You will need a reference to Microsoft ActiveX Data Objects x.x Library, unless you use late binding.Dim cn As New ADODB.Connection, cn2 As New ADODB.ConnectionDim rs As ADODB.Recordset, rs2 As ADODB.Recordset Set cn = CurrentProject.Connection Set rs = cn.OpenSchema(adSchemaTables, _ Array(Empty, Empty, Empty, "tablenamehere")) While Not rs.EOF Debug.Print rs!table_name; " desc= "; rs!Description Set rs2 = cn.OpenSchema(adSchemaColumns, _ Array(Empty, Empty, "" & rs!table_name & "")) While Not rs2.EOF Debug.Print " " & rs2!Column_Name Debug.Print " " & rs2!Data_Type Debug.Print " " & rs2!Description Debug.Print " " & rs2!Is_Nullable rs2.MoveNext Wend rs.MoveNext Wend rs.Close Set cn = NothingYou can also look at things the other way around and get a list of tables that contain a particular field.Dim cn As New ADODB.ConnectionDim rs As ADODB.RecordsetDim strTempList As String On Error GoTo Error_Trap Set cn = CurrentProject.Connection 'Get names of all tables that have a column called Set rs = cn.OpenSchema(adSchemaColumns, _ Array(Empty, Empty, Empty, SelectFieldName)) 'List the tables that have been selected While Not rs.EOF 'Exclude MS system tables If Left(rs!Table_Name, 4) "MSys" Then strTempList = strTempList & "," & rs!Table_Name End If rs.MoveNext Wend ListTablesContainingField = Mid(strTempList, 2)From: has quite a bit on the subject:

That is why we need to have an empty table in that case. The "sl_list ifd_data_fld" command returns ifd_data_seq and ifd_data_dtl_seq in the recordset. So you can create the empty recordset with these values set as 0. That way the recordset will not be empty but when you access it for the particular ifd_data_seq you will not get a row - which is what we wanted.If this functionality is used, then all segments below UC_LOAD_HOST_ORD must use this and not the traditional "sl_data_fk = :sl_data_pk" retrieve methods. This is because when creating the tables we called "release internal tables" and that also killed the table that integrator had created for this SQL to work.Referring to first gotcha - note that in MOCA if you assign one recordset to another, it just sets the pointer and does not clone the data. This implies that if you set multiple recordsets to the same "empty" recordset then even though you are thinking they are two different recordsets - they are really the same. So if you move to the last row in one - you will also move to the last row in the other. Where it would cause an issue is that when you will create the internal table from one - the next one will not work. You will need to call ".reset" on the recordset again before using it.SummaryThe basic idea is that we should try to match event output to the RedPrairie order model via this capability. That implies

Tables in Public Preview are also free to use during the preview but could incur a charge in the future.noteYou may see other system tables in your account besides the ones listed above. Those tables are currently in Private Preview and are empty by default. If you are interested in using any of these tables, please reach out to your Databricks account team.System tables relationships​The following entity relationship diagram outlines how the currently available system tables relate to each other. This diagram highlights the primary and foreign keys of each table.Enable system table schemas​Since system tables are governed by Unity Catalog, you need to have at least one Unity Catalog-enabled workspace in your account to enable and access system tables. System tables include data from all workspaces in your account but they can only be accessed from a Unity Catalog-enabled workspace.System tables are enabled at the schema level. If you enable a system schema, you enable all the tables within that schema. When new schemas are released, an account admin needs to manually enable the schema.System tables must be enabled by an account admin. You can enable system tables using system-schemas commands in the Databricks CLI or using the SystemSchemas API.noteThe billing schema is enabled by default. Other schemas must be enabled manually.List available system schemas​Use the following CLI command to list all system schemas in your account:Bashdatabricks system-schemas list METASTORE_IDThe list command returns an array of

This step is extremely efficient as it ... is simply looking at parsed ... view of inbound IFD from memory. ... If an inbound IFD was optional, e.g. ... order notes - then you still need ... to create a valid recordset with 1 row.}Now we can create another command say "create usr sap order tables" as follows:get usr sap order segments as rs|{ release internal tables ; create internal table where table_name = 'uc_sap_mysaphdr' and res = @uc_sap_mysaphdr ; ... so on for all tables}The UC_RELEASE_HOST_ORD will simply call "release internal tables" command.With that in place the ORDER_HDR, ORDER_DETAIL etc. will no longer utilize the generated retrieve method implementation that says "where sl_data_fk = :sl_data_pk" instead it will call a MOCA Command that will utilize "select from internal table" to get data from multiple inbound IFD segments utilizing joins - which is extremely efficient.This will utilize the several tables created earlier and access the data from there. It can utilize complete SQL language including group and join clauses:{ select from internal table where select_stmt = "select ... any columns from any table ...." and table_name = " uc_sap_mysaphdr join .. left outer join .." }Some GatchasNote that the internal tables are created directly from the recordset. If the recordset is empty, the table cannot be created as it does not have the column information.

Data from multiple inbound segments. So creating the intermediate EO segments is a way to circumvent that. Using the internal database we can overcome this and simply load the inbound IFD to internal databases. Afterwards we can simply join the data so that the EO also matches the result IFD:The basic difference is that we have introduced a high level segment that would load all of the relevant inbound IFDs to internal database as tables. And at the end we would release those tables. The retrieve method implementation of the UC_LOAD_HOST_ORD will utilize the "create internal table" and "insert into internal table" commands. First we need to create a component that would return a resultset for each inbound IFD segment that we are interested in. For example lets call that component "get usr sap order segments as rs". It could be implemented as:/* * During integrator execution - ifd_data_ptr is on stack * so it does not need to parse the inbound again. But * in case it is not on stack, e.g. * for testing then we get it via standard * integrator command. */if ( @ifd_data_ptr#onstack ) hide stack variable where name = 'ifd_data_seq'else sl_get ifd_data_ptr |{ /* * If an inbound IFD is optional - we need to still * create an empty recordset for it */ ... create empty recordsets | /* * Now fetch the inbound IFD Data into a * recorset, e.g. lets say inbound IFD * segment is called MYSAPHDR - we will
