RODBC Teradata Copy Table - r

Question

I am using RODBC with R to connect to Teradata.
I am trying to copy a large table EXAMPLE (25GB) from the READ_ONLY database to the WORKdatabase. The two databases are under the same DB system so I only need one connection.
I have tried sqlQuery, sqlCopy and sqlCopyTablefunctions but do not succeed.
sqlQuery
EDIT: syntax error corrected as suggested by #dnoeth.
CREATE TABLE WORK.EXAMPLE AS (SELECT * FROM READ_ONLY.EXAMPLE) WITH DATA;
OR
CREATE TABLE WORK.EXAMPLE AS (SELECT * FROM READ_ONLY.EXAMPLE) WITH NO DATA;
INSERT INTO WORK.EXAMPLE SELECT * FROM READ_ONLY.EXAMPLE;
I let the latter method run for 15h but it did not complete the copy.
sqlCopy
sqlCopy(ch,
query='SELECT * FROM READ_ONLY.EXAMPLE',
destination = 'WORK.EXAMPLE')
Error: cannot allocate vector of size 155.0 Mb
Does sqlCopy try to first copy the data to R's memory before creating the new table? If so, how can I bypass this step and work exclusively on the Teradata server? Also, the error persists even if use the option fast=F.
In case R's memory was the issue, I tried creating a smaller table of 1000 rows:
sqlCopy(ch,
query='SELECT * FROM READ_ONLY.EXAMPLE SAMPLE 1000',
destination = 'WORK.EXAMPLE')
Error in sqlSave(destchannel, dataset, destination, verbose = verbose, :
[RODBC] Failed exec in Update
22018 0 [Teradata][ODBC Teradata Driver] Data is not a numeric-literal.
In addition: Warning message:
In odbcUpdate(channel, query, mydata, coldata[m, ], test = test, :
character data '2017-03-20 12:08:25' truncated to 15 bytes in column 'ExtractionTS'
With this command a table was actually created but it only includes the column names without any rows.
sqlCopyTable
sqlCopyTable(ch,
srctable = 'READ_ONLY.EXAMPLE',
desttable = 'WORK.EXAMPLE')
Error in if (as.character(keys[[4L]]) == colnames[i]) create <- paste(create, :
argument is of length zero

Answer 1

The syntax in your sqlQuery is not correc, the WITH DATAoption is missing:
CREATE TABLE WORK.EXAMPLE AS (SELECT * FROM READ_ONLY.EXAMPLE) WITH DATA;
Caution, this will loose all NOT NULL & CHECK constraints and all indexes, resulting in the 1st column as Non-Unique Primary Index.
Either add a PI manually or switch to
CREATE TABLE WORK.EXAMPLE AS READ_ONLY.EXAMPLE WITH DATA;
if READ_ONLY.EXAMPLE is a table and you actually want an exact copy.
